ci: check out litellm-docs directly into docs/my-website

Replaces the rm-and-symlink hack with a plain actions/checkout
using path: docs/my-website. The previous approach failed on this
branch because docs/my-website no longer exists in the repo (its
parent docs/ directory was also removed), so ln -s had nowhere
to create the symlink.

Also adds the same checkout step to test-unit-documentation.yml,
which was silently relying on docs/my-website existing in-tree
for test_env_keys.py and test_router_settings.py.
