Please support gitHub actions

[asubmani]

As a:
Our Infrastructure team uses Github Enterprise and Terraform

I want:
Bedrock with 100% integration with github actions

So that:
we can begin evaluating and using Bedrock
Describe the solution you'd like:

At the very least, all current examples as is , but powered by github actions.

Acceptance Criteria:

If github actions wont be supported, please call this out explicitly as we won't rely on bedrock for gitiOps and look at Atlantis or other solutions.

Describe alternatives you've considered:
Atlantis, Flux v2, Argo CD

Additional context:

Does this require updates to documentation?:
Yes
