Review Comment:

[UpdaetSchema](https://github.com/apache/iceberg-python/blob/55bbc1863aba6646b2dc36573355aabb11909095/pyiceberg/table/__init__.py#L1920)
and implements the UpdateTableMetadata:
I agree, that's a great catch. I've now updated the class.

table.manage_snapshots, like:
Updated!
> We could also make create_tag returns ManageSnapshots itself to support
chain operations:
This is great, updated to allow method chaining!
> There are several benefits:
I do agree with the benefits. However, with this change, `ManageSnapshots`
would be specific to metadata update operations only. In my other PRs, I've
implemented `cherrypick` and `publish_changes`, both of which need to create a
new snapshot from an existing snapshot using `_MergingSnapshotProducer`. I'm
assuming we would like to have these APIs under `ManageSnapshots` like
`table.manage_snapshots().cherrypick(snapshot_id)`.
Ex:
```
class ManageSnapshots:
def cherrypick(self, snapshot_id: int) -> ManageSnapshots:
CherryPickSnapshot(snapshot_id, .....).cherrypick()
return self
```
Here, we are performing cherrypick through a class CherryPickSnapshot that
implements _MergingSnapshotProducer. So no updates or requirements are added to
ManageSnapshots and ManageSnapshots.commit() doesn't update the table. Would
this be a reasonable implementation?
