ci: removing dev comments before the release

[drodriguez-305]

Which problem does the PR fix?

This PR will remove development notes in our values and manifest files. It was requested by support as some customers have been confused by these.

#1089

What's in this PR?

Created a script that will run in our release process that will remove all TODO and NOTES sections. The script will ignore any files that are located in the "./test" directory. It will also create a change log and upload as artifact for reference.

The script will be called from our chart-release.yaml before the actual release steps.

@drodriguez-305 I like the script 😁

However, I believe it could be much simpler since we have everything in the repo.

First of all, we only need to remove the development comments, not all comments.
Second, we only need to remove the comments in static files like value.yaml file, but in the template, we can remove them by using template comments {{/* ... */}} so they will not be rendered for the end users.

So, the goal here is to simplify the script by fixing the root cause in the repo itself.
