feat: Github Actions - set working directory in step

[pixo-wnobrien]

I have a repo with a couple different projects in it, and I would like to set up a workflow that tests all the projects on a PR. It would be great if I could set the working directory in the step like below:

      - name: Check Test Coverage
        uses: vladopajic/go-test-coverage@v2
        with:
          working-directory: app1
          config: .coverage.yaml

      - name: Check Test Coverage
        uses: vladopajic/go-test-coverage@v2
        with:
          working-directory: app2
          config: .coverage.yaml

I usually use golangci-lint in the same pipeline before I run my tests, and the Github Action for that works in this way

      - name: Lint
        uses: golangci/golangci-lint-action@v3
        with:
          version: v1.54
          working-directory: ./app1

I've tried many different workarounds, but I'm having a hard time getting it to work in my repo with multiple projects without this feature. If there are any suggestions that would be greatly appreciated! I put my workflow file below for reference

jobs:
  test-app1:
    runs-on: ubuntu-latest

    defaults:
      run:
        working-directory: ./app1

    steps:
      - uses: actions/checkout@v3

      - name: Setup Go
        uses: actions/setup-go@v4
        with:
          go-version: '1.21'

      - name: Lint
        uses: golangci/golangci-lint-action@v3
        with:
          version: v1.54
          install-mode: "goinstall"
          args: --timeout=30m
          working-directory: ./app1

      - name: Run Tests
        run: make test

      - name: Check Test Coverage
        uses: vladopajic/go-test-coverage@v2
        with:
          config: app1/.coverage.yaml

  test-app2:
    runs-on: ubuntu-latest

    defaults:
      run:
        working-directory: ./app2

    steps:
      - uses: actions/checkout@v3

      - name: Setup Go
        uses: actions/setup-go@v4
        with:
          go-version: '1.21'

      - name: Lint
        uses: golangci/golangci-lint-action@v3
        with:
          version: v1.54
          install-mode: "goinstall"
          args: --timeout=30m
          working-directory: ./app2

      - name: Run Tests
        run: make test

      - name: Check Test Coverage
        uses: vladopajic/go-test-coverage@v2
        with:
          config: app2/.coverage.yaml

permissions:
  contents: read

I can configure the step to use the corresponding cover.out file, but since the step is not running in the directory that the tests were run in I get the following error:

failed to generate coverage statistics: could not find file [github.com/org/repo/app1/docs/docs.go]: can't find "docs.go": no required module provides package github.com/org/repo/app1/docs: go.mod file not found in current directory or any parent directory; see 'go help modules'
