chore: update lance dependency to v12.0.0-beta.15 (#4143)

Updates the Rust workspace Lance dependencies, Cargo lockfile, and Java
lance-core from v12.0.0-beta.14 to
[v12.0.0-beta.15](https://github.com/lance-format/lance/releases/tag/v12.0.0-beta.15).
No compatibility fixes were required; `cargo clippy --quiet --workspace
--tests --all-features -- -D warnings`, `cargo fmt --all --quiet`, and
`git diff --check` passed.
