chore!: update lance dependency to v9.0.0-rc.1 (#3673)

Browse Source 
BREAKING CHANGE: splits generated by the permutation data loader will
not be the same, due to a change in hash function.

Updates the Lance dependencies and Java lance-core to
[v9.0.0-rc.1](https://github.com/lance-format/lance/releases/tag/v9.0.0-rc.1).
Includes the required DataFusion 54 and Lance file-reader compatibility
updates.
