[PYTHON][bugfix] Fix missing post-params when content type is json

[ilayu-blip]

This fixes issue #23457

I have made the fix to be non-destructive. If this issue did not happen to you then this fix will not BREAK anything.

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)

Summary by cubic

Fixes missing post_params for JSON requests in Python clients by sending them as the JSON payload when body is empty. Also updates .gitignore to ignore artifacts from run-in-docker.sh (refs #23457).

• Bug Fixes

  • Add JSON fallback across templates: python/asyncio, python/tornado, python/httpx, python-pydantic-v1/asyncio, python-pydantic-v1/tornado, python-pydantic-v1; regenerated Python samples to match.
  • Serialize via json.dumps(...) or args["json"], using dict(post_params) when body is None.

• Misc

  • Update .gitignore to exclude run-in-docker.sh generated artifacts.

^{Written for commit 5719862. Summary will update on new commits.}
