[FEATURE]: Switch to Coveralls Action

[trevorb1]

Feature Request

Coveralls recommends using their GitHub Action for CI. Currently, we manually upload to coveralls through the following:

- name: Upload coverage data to converalls.io
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
  if: matrix.os == 'ubuntu-latest' && matrix.python-version == '3.11'
  run: |
    pip install --upgrade coveralls
    coveralls --service=github

Is your feature related to a bug?

No response

Suggested Solution

Should be something similar to

- name: Upload coverage data to converalls.io
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
  if: matrix.os == 'ubuntu-latest' && matrix.python-version == '3.11'
  uses: coverallsapp/github-action@v2
