feat: Add HIDE_ITEMS_LIST environment variable to hide individual items table in reports

[Copilot]

Add HIDE_ITEMS_LIST environment variable to hide issue/PR details table

Summary

Successfully implemented a new environment variable HIDE_ITEMS_LIST that allows users to hide the individual items table in the generated report while keeping all summary metrics visible. This addresses the feature request to provide management with only aggregated metrics without the detailed list of issues/PRs.

Implementation Checklist

• Add new hide_items_list boolean attribute to EnvVars class in config.py
• Read HIDE_ITEMS_LIST environment variable in get_env_vars() function (default to False for backward compatibility)
• Update EnvVars.__init__() to accept hide_items_list parameter
• Update EnvVars.__repr__() to include hide_items_list
• Modify write_to_markdown() in markdown_writer.py to conditionally skip writing the items table when hide_items_list is True
• Add comprehensive tests for the new functionality
• Update README.md to document the new environment variable
• Run linting and tests to validate changes
• Manually verify the implementation works correctly
• Request and address code review feedback
• Run prettier on markdown files to fix linting issues

Test Results

✅ All 135 tests pass (up from 133 - added 2 new tests)
✅ Code coverage: 91.42%
✅ Linting: 10.00/10 rating
✅ Manual testing verified correct behavior
✅ Prettier formatting applied to all markdown files

Behavior

• Default (HIDE_ITEMS_LIST=false): Shows summary metrics + count table + individual items table
• When HIDE_ITEMS_LIST=true: Shows summary metrics + count table only (items table is hidden)

Backward Compatibility

The default value is false, ensuring all existing workflows continue to work without any changes. Users must explicitly set HIDE_ITEMS_LIST=true to hide the items list.

This section details on the original issue you should resolve

<issue_title>Add env_var to include issue/PR list in the report</issue_title>
<issue_description>### Is your feature request related to a problem?

Right now, Managment only wants to view the statistics and not the details of the report. So, they're not interesested in the list of PRs involved in the metrics.

Describe the solution you'd like

Right now, by default, the list of issues or PRs is included in the report, with no option to exclude it.

It would be ideal to have a new environment variable, maybe called HIDE_ISSUE_LIST (or similar), set to "false" by default (to respect backwards compatibility), to choose if the Issue list should be included in the report or not.
If this new environment variable is set to "true", then report would only include aggregated metrics, like in the following image:

Describe alternatives you've considered

I have considered the possibility of altering the report file once created, to remove the last table, containing the issue list. But for the sake of maintainability, it would be ideal to have this feature as part of the GH Action.

Done! Ran prettier on README.md and fixed the trailing whitespace issue. All markdown files now pass prettier formatting checks.
