Use version from module and another version in matrix testing

Description:
Describe your proposal.

I want to be able to do something like this where the used Go versions are set automatically in matrix testing without having to manually maintain the workflows. This is very useful when having many repositories with CI/CD infrastructure set up. To minimize the versions of Go used for testing, I want to test with the latest stable and the minimum version that the project supports, i.e. I want to use stable and the version from my go.mod file.

My idea is to be able to specify something like go-version-file inside the go-version field:

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        go: [ 'go.mod', 'stable' ]
    name: Go ${{ matrix.go }} sample
    steps:
      - uses: actions/checkout@v4
      - name: Setup go
        uses: actions/setup-go@v4
        with:
          go-version: ${{ matrix.go }}
      - run: go run hello.go
