Rector version	dev-main

When rector is run with the --clear-cache option, the cache is cleared 2x.

The first time here https://github.com/rectorphp/rector-src/blob/b163af7942a0e7ba09a75238362eca373a915194/src/Console/Command/ProcessCommand.php#L209 and the second time https://github.com/rectorphp/rector-src/blob/b163af7942a0e7ba09a75238362eca373a915194/src/FileSystem/FilesFinder.php#L115

I guess one clearing of cache should be enough

For safer usage, it can be reduced with clear early on debug, clear later on --clear-cache option.

I created PR:

• [Cache] Fix double clear-cache rector-src#8096

for it.
