Add poetry.lock back to versioning and trying minimal dependency (#400)

- [x] Added `poetry.lock` back to version control
- [ ] ~Removed pinning of poetry version in GitHub Actions~
- [ ] ~Pruned dependency list to the minimal required one based on the
dependencies that already bring in other packages that are needed.~
- [x] figure out why the error was occurring:
- So `linkml-runtime` has a dependency on `prefixcommons` which has a
dependency on `pytest-logging`. This package (pytest-logging) is causing
issues with the windows instance within GitHub Actions.
- I do not know why this is **not** happening in any of the other
projects we have.
  - The fix in `qc.yml` is : 
  ```
    poetry run pip wheel --use-pep517 "pytest-logging (==2015.11.4)"
  ```
    before `poetry install`

- Another issue was with Windows environment not detecting `poetry` as a
command in spite of being installed.
- Reason: `poetry` path was not automatically being added to environment
variables when it is invoked using an reusable gh-action (
`snok/install-poetry@v1`).
   - Fix:
    ```
    - name: Windows specific step.
            if: matrix.os == 'windows-latest'
run: echo "${HOME}/.local/bin" | Out-File -FilePath $env:GITHUB_PATH
-Encoding utf8 -Append

    ```
- `pyparsing` is not really used in the project as far as I know. It is
also causing errors in GH Actions. So removing it

Note: `poetry` is still pinned to version 1.3.2 as before.
