[SPARK-35378][SQL][FOLLOWUP] Restore the command execution name for DataFrameWriterV2

[cloud-fan]

What changes were proposed in this pull request?

This is a followup of #32513

It's hard to keep the command execution name for DataFrameWriter, as the command logical plan is a bit messy (DS v1, file source and hive and different command logical plans) and sometimes it's hard to distinguish "insert" and "save".

However, DataFrameWriterV2 only produce v2 commands which are pretty clean. It's easy to keep the command execution name for them.

Why are the changes needed?

less breaking changes.

Does this PR introduce any user-facing change?

no

How was this patch tested?

N/A
