Maxim Gekk 310c14ac8d [MINOR][SQL] Add a comment for removedSQLConfigs
### What changes were proposed in this pull request?
In the PR, I propose to explain in the description of `removedSQLConfigs` when removed SQL configs should NOT be placed to the map.

### Why are the changes needed?
To make the cases when SQL configs should be added to `removedSQLConfigs` more clear. Recently, `spark.sql.variable.substitute.depth` was removed from the map by #27646 because it contradicts to the condition described by the PR.

### Does this PR introduce any user-facing change?
No

### How was this patch tested?
By `./dev/scalastyle`

Closes #27653 from MaxGekk/removedSQLConfigs-comment.
