fix: correct triage agent paths

[fancydirty]

Summary

Fixes import paths for the ADK issue and pull request triaging workflows.

The workflows previously set PYTHONPATH to contributing/samples, but both packages live under contributing/samples/adk_team:

• contributing/samples/adk_team/adk_pr_triaging_agent
• contributing/samples/adk_team/adk_triaging_agent

As a result, the PR triage job could fail before it could run:

ModuleNotFoundError: No module named adk_pr_triaging_agent

This PR changes both triage workflows to use PYTHONPATH=contributing/samples/adk_team.

It also fixes the PR triaging agent CONTRIBUTING.md lookup. The previous parents[3] path resolved to contributing/CONTRIBUTING.md, but the file is in the repository root, so the correct path is parents[4] / CONTRIBUTING.md.

testing plan

Verified locally with corrected PYTHONPATH and dummy workflow environment variables in the Python 3.10 uv test environment.

Command summary:

GITHUB_TOKEN=dummy PULL_REQUEST_NUMBER=1 ISSUE_NUMBER=1 ISSUE_TITLE=test ISSUE_BODY=test EVENT_NAME=issues PYTHONPATH=contributing/samples/adk_team UV_PROJECT_ENVIRONMENT=.venv310 uv run --python 3.10 --extra test python -c inline_module_spec_check

Verification output:

adk_pr_triaging_agent: True
adk_pr_triaging_agent.main: True
adk_triaging_agent: True
adk_triaging_agent.main: True

Hi @rohityan, thanks for the review. I updated the PR description to include a dedicated testing plan section and local verification output for the corrected PYTHONPATH/module resolution. I also refreshed the branch checks after the old failed run; current PR checks are green on my side.
