fix(csharp): update hiveserver2 submodule to fix HTTP path query encoding (#341)

## Summary

- Updates the `hiveserver2` submodule to the latest `main` which
includes the fix for `UriBuilder` percent-encoding `?` as `%3F` in HTTP
paths containing query parameters (e.g.
`/sql/1.0/warehouses/<id>?o=<orgId>`)
- This caused connection failures for Databricks warehouse paths that
include an org ID suffix

## Upstream fix

adbc-drivers/hiveserver2#26

## Test plan

- [ ] Verify connection succeeds with HTTP path containing `?o=<orgId>`
query parameter
