Add workflow to test TypeScript clients

[wing328]

Add workflow to test TypeScript clients (migrate from CircleCI workflow)

Currently, only test with Node 20.x but we can easily test other node versions in the workflow.

Comment out some tests which failed or the folders do not contain pom.xml yet.

For a list of errors with the failed tests, please refer to https://github.com/OpenAPITools/openapi-generator/actions/runs/18489477998/job/52679530366?pr=22126

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package || exit
  ./bin/generate-samples.sh ./bin/configs/*.yaml || exit
  ./bin/utils/export_docs_generators.sh || exit
  

  (For Windows users, please run the script in WSL)
  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  IMPORTANT: Do NOT purge/delete any folders/files (e.g. tests) when regenerating the samples as manually written tests may be removed.
• File the PR against the correct branch: master (upcoming 7.x.0 minor release - breaking changes with fallbacks), 8.0.x (breaking changes without fallbacks)
• If your PR solves a reported issue, reference it using GitHub's linking syntax (e.g., having "fixes #123" present in the PR description)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

Sorry accidentally pressed the merge button. Happy to revert the change or file another one on top if anyone spots any issues with the change 🙏

these tests for angular 16 should be re-enabled or ported to angular 19: https://github.com/OpenAPITools/openapi-generator/tree/master/samples/client/petstore/typescript-angular-v16-provided-in-root/tests/default/src

currently, no angular unit test runs as part of the PR checks.

thanks for the review

let me re-enable it tomorrow with a PR

if it passes in circleci, it should also pass in the github workflow
