ci: standardize docs workflow

[stefan-jansen]

Summary

• standardize the library docs deployment workflow on the shared website handoff pattern
• pin astral-sh/setup-uv to the official v8.1.0 commit from Astral's setup-uv documentation
• build docs with uv run mkdocs build and deploy site/ to website/static/docs/models/ when the deploy key is present

Notes

• preserves the existing website-side docs rendering and navbar injection contract
• keeps the deploy target and URL structure unchanged

Pull request overview

Standardizes the documentation deployment workflow to follow the shared “website handoff” pattern, including pinning the setup-uv action and deploying the built MkDocs site to the website repository when a deploy key is available.

Changes:

• Update the docs workflow to use a pinned astral-sh/setup-uv commit (v8.1.0).
• Build docs via uv run mkdocs build and deploy site/ into website/static/docs/models/ when DOCS_DEPLOY_KEY is present.
• Update the checkout action reference in the docs workflow.

Dropping --strict from the MkDocs build step reduces CI signal (warnings like broken links no longer fail the job). If the intent is to keep docs quality gates, consider restoring --strict or adding an explicit rationale/alternative check so regressions don’t get deployed.
