Delete branch on PR merge

[damacus]

Add the github action to remove merged branches.

Addressed in #113

Unfortunately the documentation in jessfraz/branch-cleanup-action is out of date. I've taken a pass at following the syntax, but the action is not actually deleting the branch at the moment https://github.com/sous-chefs/meta/blob/master/.github/workflows/main.yml

Something to poke some more and see if maybe it needs a run command or if that script is actually working.

[JohnRoesler]

Thank you @PowerSchill for solving this one - needed to be run on closed action https://github.com/sous-chefs/meta/blob/master/.github/workflows/main.yml#L5

[PowerSchill]

Reopening so I can track implementation.

Github now supports this natively but did not expose the setting in the v3 or v4 api.

[JohnRoesler]

I can confirm it's there in the settings. So much for a cool GitHub action to take care of it

[PowerSchill]

Yeah, I saw that but also noticed the terraform provider for GitHub didn't seem to support that setting. The actions do open up possibilities for other things so as a learning experience it was valuable.

all merged

We decided to use the github action route to auto delete branches as the github api does not have the delete branch setting exposed and so we can't work that into the terraform provider
