Add proper lockfile generation and CI validation for Python dependencies used in documentation building. Changes: - Rename requirements-min/requirements.txt to requirements.in (unpinned deps) - Replace pip freeze with uv pip compile for lockfile generation - Add update-deps target for regenerating lockfile - Add verify-deps target for CI validation - Add CI job to verify lockfile stays in sync with requirements.in The lockfile (requirements.txt) is generated using uv with: make -C Documentation update-deps Developer workflow: 1. Edit requirements.in to add/update dependencies 2. Run: make -C Documentation update-deps 3. Commit both requirements.in and requirements.txt This enables: - Security vulnerability management via exact version tracking - Build reproducibility across environments - Audit trail for dependency changes Signed-off-by: Sean Meyer <sean.meyer@datadoghq.com>

Add Python dependency lockfile
Why
Lockfiles pin all dependencies (direct and transitive) to specific versions, enabling:
Security vulnerability management: Automated tools can quickly identify which repositories are affected by CVEs without needing to run dependency resolution.
Incident response: When issues occur, lockfiles provide an audit trail showing exactly which dependency versions changed and when.
Build reproducibility: Eliminates dependency drift between environments and over time.
