VACUUM doesn't create a commit in transaction log

[ion-elgreco]

When you vacuum a table with delta-rs, it doesn't create a commit in the delta transaction log, stating the VACUUM operation.

Does it do that in Spark? I wouldn't expect it to create a transaction.

@wjones127 apparently they do since this PR: delta-io/delta#1552

Also here is an example: https://books.japila.pl/delta-lake-internals/demo/vacuum/#vacuum-retain-0-hours at the bottom of the page.

@wjones127 I checked my tables written with databricks, and they all have the VACUUM START/END commits
