Change CI/CD to support ACT

[laurensWe]

Intro

act is a cli tool that lets you run GitHub actions locally (faster iteration). Unfortunately, it works slightly different than GitHub actions, but this can be fixed with some small changes in the ci/cd so that both GitHub actions and act work.

Implementation notes

• act docs

Acceptance Criteria

• CI/CD of amt works with GitHub actions and act (.github/workflows/ci.yaml)

Out of Scope

• CI/CD of ai-validation-infra works with GitHub actions and act
• CI/CD of ai-validation works with GitHub actions and act

this (nektos/act#1518) May be related to this, because if one job fails/finishes in the matrix then it is stuck.
