Review Comment:
Most of the code here are similar to Spark's `ResolveReferences`. Could you
make a note of this and add docs before `case
mO@MatchMergeIntoTable(targetTableO, sourceTableO, _)` to summarize the custom
changes?

Review Comment:
Also, is the code copied from Spark 3.2? Any difference among Spark 3.2,
3.3, and 3.4?

Review Comment:
For Spark 3.0 and 3.1, have you checked if the code here is different from
Spark's `ResolveReferences`. Given we introduce the custom rule here, we
should still match the implementation of `ResolveReferences` in Spark except
for the custom logic you added.
