Automatically clean up the harbor mirror warehouse script

Automatically clean up the harbor mirror warehouse script

Please read the instructions before proceeding, and will not be responsible for excessive deletions.

There was a problem with the deletion of the version found on the Internet, and certain modifications were made.
The mirror images here are all constructed according to the normal order of numbers. E.g

v:1.0.1
v:1.0.2
v:1.0.3
v:1.0.4
OLD_VERSION_NUM设置为3的话 会把v:1.0.1删除。只保留后3个。
