Update SDK menu links to point directly to docs

Updates SDK menu links in navbar and footer to point to /docs/overview
instead of landing pages, consistent with the removal of SDK landing pages.

Changes:
- Update JavaScript SDK link from /sdk/js/ to /sdk/js/docs/overview
- Update Python SDK link from /sdk/python/ to /sdk/python/docs/overview
- Remove outdated comments about trailing slashes
