Add workflow to release chart and expose via GitHub Pages

[carlreid]

This workflow makes use of the helm/chart-releaser-action which will automatically create a git tag whenever the the chart version changes.

This will cause a release to be deployed under your releases with a referenced tgz of the chart (example). After that, the action will create/update and index.yaml on the gh-pages branch (example) and allow people to use helm repo add meilisearch https://meilisearch.github.io/meilisearch-kubernetes

Note: You'll want to create a gh-pages branch first before merging this. You can create an empty branch like this:
git checkout --orphan gh-pages git rm -rf .

I also created an index.md (example) which you could use to add some instructions. Here's what it could like.

Once you push the new branch, then modify the repo settings to be like:

Then all should be good 🙈

Resolves #13

[carlreid]

Just to be clear, I used an index.md. Might be better to use a markdown file if you want it "README" like, though I think a html file will be fine.

But otherwise yes, it should just work fine. You can check the action run and such on my fork. Nothing else needs to be changed 😊

Sure! Indeed, it would be preferable to use markdown, and we will populate it and make it look nicer :)

I'll change this and merge the PR!

Thanks again! 🎉 🎉 🎉

@eskombro Seems to be working great, also good job on the better looking index.md 😄 Thanks for reviewing so quickly 👍

Great, I was surprised with the timeout for merging, but seems to be a Bors problem. I just tested everything and works perfectly! Thanks 🚀
