Truncate issue

[maryliag]

Workflow is failing for large repo with hundreds of PRs (e.g. opentelemetry-collector-contrib), because of the limit of characters on the issue body.
This PR adds an option to limit the amount of PRs per section and also to skip draft entirely.

[Copilot]

Pull request overview

Adds configurability to prevent the Pull Request Dashboard issue body from exceeding GitHub’s issue-body size limit in very large repositories by allowing row truncation per section and optionally omitting drafts.

Changes:

• Introduces max_rows_per_section to cap rendered rows per routing section (and drafts) and adds a “More X PRs not shown” truncation note.
• Introduces skip_drafts to optionally omit the Draft pull requests section entirely.
• Wires both options through the reusable workflow inputs, repository configuration, CLI flags, and rendering logic.

• --max-rows-per-section accepts negative values today; because the value is later used for slicing, a negative number would drop rows from the end and compute an incorrect truncation count. Since the flag documents 0 = no limit, reject values < 0 during argument validation.
