Use Helm release action that works with tags

[treydock]

This is message from Github Action using official Helm chart:

Discovering changed charts since 'v0.1.1'...
Nothing to do. No chart changes detected.

This is long standing and very annoying issue with Helm's official chart where it doesn't want to do releases on tags. The only place I have been able to use the Helm official action is repos not using tags to handle releasing a chart. On several projects I contribute to and many I manage, I've had to use third party actions to handle releases to gh-pages for Helm charts.

Upstream PR that might fix this but currently not merged: helm/chart-releaser-action#96. There are several issues on that repo about not being able to publish with tags.

you're right, I tried to understand what the official releaser does but it indeed messes with tags.
even tried committing without a tag but without success.
Merging again your third-party solution, could you just please specify a specific version of the third-party gh-action instead of latest please?

I've subscribed to the official gh-pages helm releaser PR for tags, will check it once they merge it
