Gradle keeps the wrapper's dist zip in the .gradle folder after unzipping, using double the space

[altrisi]

Expected Behavior

Gradle should remove the wrapper's dist zip file after it has been unzipped right next to it.

Current Behavior

The zip is kept, wasting double the space on the hard drive for a no longer used file.

Context

I was looking at cleaning disk space by removing some of my old files, and thought about removing old wrapper distributions. To my surprise, when I opened the {userdir}/.gradle/wrapper/dists folder, I found that each wrapper I had used also kept the zip file that was used to download it, therefore wasting double the space. Given each one of those distributions are over 100MB each zipped (with Gradle 7.3's zip being 110MB on my machine), this is an enormous waste of space, specially if you have multiple wrapper versions from normally updating Gradle. In my case I had 12 versions, meaning that over 1GB was wasted storing only the unused zips.

Steps to Reproduce

• Run some gradle script that causes the download of a distribution.
• Go to {userdir}/.gradle/wrapper/dists/gradle-{version}-bin/{random characters}.
• Find that there's a zip whose contents are unzipped directly next to it
