feat: Add Deploy Action

[kylemellander]

This is a new action that helps to deploy our JavaScript libraries to its consumers within the organization.

It does the following things:

• Looks for repos that depend on the library (overridable with only, with include and exclude likely in the future)
• Creates PRs in those projects.
• Allows for custom commands for monorepos through configuration.
• Adds the ability to auto-merge those PRs.
• Reports all the PRs created
• Fails if any PRs fail to create - reporting both failures and successes (1 project failure does not stop all releases)

Where is this used/tested

This action as of yet, is not in use, but has been tested in https://github.com/planningcenter/test-js-auto-deploy-pkg and https://github.com/planningcenter/test-js-auto-deploy-consumer

I'm with @seven1m on this one. I know enough bash to write a couple one-liners here and there, but this is more complicated than I'm personally comfortable actually reviewing for any kind of completeness or bugs. Is it on the table to have this much logic in a language we're collectively more comfortable writing/reading/testing?

@danielma @seven1m thanks for the push to do it in ruby. It is a lot more code to set up the infrastructure, but I think its easier to grep.
