Add missing endpoints to Reactions

Resolves #1633

Before the change?

There were no endpoints to get a release's reactions, create a release reaction or delete a release reaction

After the change?

I added those endpoints to the Client::Reactions module

I'm having an issue trying to run the tests I've written. I've exported a OCTOKIT_TEST_GITHUB_TOKEN with a new token I've created before forking the app (the token has all the rights I could give it) but despite doing that I get a Octokit::Unauthorized: POST https://api.github.com/user/repos: 401 - Bad credentials error.

I've tried another token that I use in my personal repos and it fails too so I don't think the issue comes from the tokens but probably from something I haven't set up proprelly.

Because of that I haven't been able to assert passing tests and complete coverage yet.

My set up process was to fork the repo then

git clone ...
cd octokit.rb
script/bootstrap
export OCTOKIT_TEST_GITHUB_TOKEN=...
script/test

@nickfloyd Maybe you'd have some insights to help me finish this PR ? 🙏

Are you able to run the tests on the main branch following those steps? When I run ./script/test on main I get the following output:

On your branch, I see the errors present in CI. There's a code problem to be addressed here before tests are runnable.

Hey @kfcampbell Yeah I'm able to run the test on main just fine, that's because the cassettes already have all the http responses stored in json files so they don't need to make a new one per test.

In the case of my 3 tests though those cassettes don't exist yet so an actual http request need to be made and that's the issue. If I were to take this test for example :

describe Octokit::Client::Reactions do
  before do
    Octokit.reset!
    @client = oauth_client
  end

  context 'with repository', :vcr do
    before(:each) do
      @repo = @client.create_repository('an-repo', auto_init: true)
    end

    after(:each) do
      @client.delete_repository(@repo.full_name)
    rescue Octokit::NotFound
    end

    context 'with release' do
      before do
        @release = @client.create_release(@repo.full_name, 'v1.0.0')
        @reaction = @client.create_release_reaction(@repo.full_name, @release.id, '+1')
      end

      describe '.release_reactions' do
        it 'returns an Array of reactions' do
          reactions = @client.release_reactions(@repo.full_name, @release.id)
          expect(reactions).to be_kind_of Array
          assert_requested :get, github_url("/repos/#{@repo.full_name}/releases/#{@release.id}/reactions")
        end
      end # .release_reactions
    end
  end
end

I get this error

1) Octokit::Client::Reactions with repository with release .delete_release_reaction deletes the reaction
     Got 0 failures and 2 other errors:

     1.1) Failure/Error: raise error

          # ./spec/octokit/client/reactions_spec.rb:15:in `block (3 levels) in <top (required)>'

So the issue is not coming from my code (yet), my code has not even be executed by the test because I'm unable to create the @repo despite doing export OCTOKIT_TEST_GITHUB_TOKEN=<<token>> or export OCTOKIT_TEST_GITHUB_TOKEN=Bearer <<token>> in my terminal before running the tests

I've spent a little while longer looking at this. I'm able to regenerate the spec file by setting the environment variable OCTOKIT_TEST_VCR_RECORD to true and then running bundle exec rspec spec/octokit/client/reactions_spec.rb:148.

Doing this gives me some failure output:

Which appears to be relevant. Do you have thoughts on that?

Yes, thank you so much @kfcampbell The first error was because I was using the wrong delete method in my DELETE test. delete_issue_reaction instead of delete_release_reaction because I didn't pay enough attention when copying an existing test.

The second error was caused because I was creating another reaction in my before do instead of only inside the DELETE test which is where I needed it. Because of that the POST request was executed 2 times instead of 1.

Both errors are fixed and all tests pass now 🙌
