Looks like there're two cases for crc files in test resources, whether automatically created or not.

#22170 was to prevent the case for adding sql/core/src/test/resources/.?.delta.crc to repo (on reflecting review comment in #21733), but there're other crc files for parquet test files.

After this PR I have to narrow down ranges when executing git add against sql/core.

Maybe adding sql/core/src/test/resources/.?.delta.crc to .gitignore helps? With the change we can narrow down the actual things to ignore. If it makes sense I'll craft a quick fix.

@HeartSaVioR that could be fine, but what is the problem? I'm not clear. Files that are in git should not be covered by ignore rules. .crc files that are created by tests should be ignored, but they should be under target/ which is already ignored.

Never mind. Looks like I added these files to #22170 but forgot to delete them. This patch made them reappear. Sorry for false alarming.
