fix: Pass snapshot_id as kwarg to RemoveStatisticsUpdate (#2694)

<!-- Closes #${GITHUB_ISSUE_ID} -->
Closes #2558 

# Rationale for this change
When removing snapshots with statistics, `RemoveStatisticsUpdate` was
being instantiated with a positional argument, which, as suggested by
@vndv, "violates Pydantic's BaseModel requirement that all fields be
passed as keyword arguments". Shout out to @vndv for catching this 🚀

This caused a `TypeError: BaseModel.__init__() takes 1 positional
argument but 2 were given` when calling
`table.maintenance.expire_snapshots().older_than(...).commit()`.

## Are these changes tested?
Yes, and a new test was added.

Existing tests only tested the `RemoveStatisticsUpdate` directly, but
didnt test the code path through `RemoveSnapshotsUpdate` that triggers
the bug.

Added `test_update_remove_snapshots_with_statistics` to
`test_expire_snapshots.py` to extend coverage for the condition.

## Are there any user-facing changes?
No.
