ci: make rust ci faster, get ci green (#2782)

* Add `ci` profile for smaller build caches. This had a meaningful
impact in Lance, and I expect a similar impact here.
https://github.com/lancedb/lance/pull/5236
* Get caching working in Rust. Previously was not working due to
`workspaces: rust`.
* Get caching working in NodeJs lint job. Previously wasn't working
because we installed the toolchain **after** we called `- uses:
Swatinem/rust-cache@v2`, which invalidates the cache locally.
* Fix broken pytest from async io transition
(`pytest.PytestRemovedIn9Warning`)
* Altered `get_num_sub_vectors` to handle bug in case of 4-bit PQ. This
was cause of `rust future panicked: unknown error`. Raised an issue
upstream to change panic to error:
https://github.com/lancedb/lance/issues/5257
* Call `npm run docs` to fix doc issue.
* Disable flakey Windows test for consistency. It's just an OS-specific
timer issue, not our fault.
* Fix Windows absolute path handling in namespaces. Was causing CI
failure `OSError: [WinError 123] The filename, directory name, or volume
label syntax is incorrect: `
