feat: Add support for repository search query to optimize repo enumeration

[Copilot]

Summary

This pull request introduces support for a new REPOSITORY_SEARCH_QUERY feature, enhances documentation, and includes minor updates to workflows and code. The most significant changes involve adding the ability to filter repositories using a search query, updating the README.md to reflect this feature, and modifying the env.py and evergreen.py files to handle the new functionality.

This allows GitHub Search API (github_connection.search_repositories) instead of enumerating all organization repositories. This allows callers to supply queries like:

org:my-org is:repository archived:false created:>2025-07-01

and only iterate over matching repositories up‑front, saving time and API rate limits. Existing behavior remains unchanged when the variable is not set, and all existing unit tests continue to pass.

Fixes #372.

Details

New Feature: Repository Search Query Support

• Environment Variable Addition: Added support for the REPOSITORY_SEARCH_QUERY environment variable in env.py. This allows filtering repositories using a GitHub Search API query. Updated the get_env_vars function to validate that at least one of ORGANIZATION, REPOSITORY, or REPOSITORY_SEARCH_QUERY is set. [1] [2] [3] [4]
• Repository Iterator Update: Modified get_repos_iterator in evergreen.py to handle repository filtering via the search query. If REPOSITORY_SEARCH_QUERY is set, the GitHub Search API is used to retrieve matching repositories.
• Main Function Update: Updated the main function in evergreen.py to pass the search_query parameter to get_repos_iterator. [1] [2]

Documentation Updates

• Workflow Example: Added an example workflow to the README.md demonstrating how to use the REPOSITORY_SEARCH_QUERY variable in a GitHub Actions workflow.
• Documentation Enhancements: Updated the README.md to include REPOSITORY_SEARCH_QUERY as a supported variable, explaining its purpose and usage. Improved clarity in other sections, such as linking to GitHub documentation for encrypted secrets. [1] [2]

Minor Improvements

• Super-Linter Workflow: Enabled automatic fixing of Markdown files by setting FIX_MARKDOWN_PRETTIER: true in .github/workflows/super-linter.yaml.
• Code Comments: Added a # pragma: no cover comment in env.py to exclude certain branches from test coverage.

Testing

@copilot can you fix the failed github action job that reports that the MARKDOWN_PRETTIER linter is failing?

Pull Request Overview

This PR introduces a new feature to optimize repository enumeration by adding support for GitHub Search API queries through the REPOSITORY_SEARCH_QUERY environment variable. This allows users to filter repositories upfront using search queries instead of enumerating all organization repositories, potentially saving API rate limits and processing time.

• Adds REPOSITORY_SEARCH_QUERY environment variable support to use GitHub Search API for targeted repository filtering
• Updates documentation to describe the new search query functionality
• Enables markdown prettier formatting in the super-linter workflow

Added a new test test_get_repos_iterator_with_search_query covering the search_query path (commit fed4054). Let me know if any adjustments are needed!
