Add Dependabot coverage

[SamErde]

Summary

Adds .github/dependabot.yml to keep the repository's dependencies automatically up to date.

Coverage

Ecosystem	Directory	Schedule	Labels
github-actions	/	Monthly	dependencies, github-actions
pip	/Docs	Monthly	dependencies, python

Details

• GitHub Actions — monitors all workflow files under .github/workflows\ for action version updates (e.g. actions/checkout, actions/setup-python, oxsecurity/megalinter, etc.)
• Python (pip) — monitors \Docs/requirements.txt\ which pins MkDocs and related docs-build dependencies (mkdocs, mkdocs-material, jinja2, pygments)

Monthly schedule keeps noise low while still catching security patches and compatibility fixes in a timely manner.

No-change areas

• No Pester tests added or modified
• No unrelated workflow changes
