[samsonasik]

Closes rectorphp/rector#9079

implemented 🎉 /cc @FlyveHest

for note: this may or may not always works for detecting type, due to phpstan nature, create a random php file will cause possible issue if process is cut in the middle, and parallel will create at least 2 files, so that's not the solution.

This PR make register file without extension after filter file extension.
