Tests for --with-repl are flaky on windows

See #10996

The tests on windows fail with

```
D:\a\_temp\cabal-testsuite-12064\cabal-multi.dist\work\.\dist\multi-out-63884\paths\cabal-with-repl-exe-0.1.0.0-inplace-test-exe: removeDirectoryRecursive:removeContentsRecursive:removePathRecursive:removeContentsRecursive:removePathRecursive:DeleteFile "\\\\?\\D:\\a\\_temp\\cabal-testsuite-12064\\cabal-multi.dist\\work\\dist\\multi-out-63884\\paths\\cabal-with-repl-exe-0.1.0.0-inplace-test-exe": permission denied (The process cannot access the file because it is being used by another process.)
```

It appears the tests work fine but then the error happens during cleanup. Therefore the tests are skipped on CI on windows.

Start by reading #10996 and locating the tests for --with-repl, then reproduce or inspect the Windows cleanup failure described here. Done means the tests are no longer skipped on Windows and their cleanup completes without the permission-denied error.
