$GITHUB_STEP_SUMMARY support

[hitmands]

Is your feature request related to a problem? Please describe.
It would be helpful to output a summary of the test coverage as ${GITHUB_STEP_SUMMARY} so
people could use a quick glance at how things went during the test run.

Describe the solution you'd like

- name: Unit Testing (Coverage)
  uses: paambaati/[email protected]
  env:
    CC_TEST_REPORTER_ID: ${{ secrets.CODE_CLIMATE_TOKEN }}
  with:
    summary: true
    coverageCommand: yarn test --coverage
    coverageLocations: |
       ${{ github.workspace }}/package-one/*/dist/vitest-coverage/lcov.info:lcov
       ${{ github.workspace }}/package-two/*/dist/vitest-coverage/lcov.info:lcov

echo "${{ combined_coverage }}" >> $GITHUB_STEP_SUMMARY

Describe alternatives you've considered
Alternatively, just output the combined coverage, and leave it to the
user to direct the output somewhere

${{ steps.coverage.outputs.report }}

Additional context

• Coverage should be combined to allow for monorepos and partial coverage files
• The output should either be markdown, or json, to easily consume it

@hitmands Can you show me what an ideal output should look like? The tool only passes on the coverage output files to CC reporter, so it doesn't understand really understand coverage.
