[lldb][test] Rename reverse-execution/TestReverseContinueNotSupported.py

Otherwise `lldb-dotest` fails with:
```
Traceback (most recent call last):
  File "/Users/jonas/Git/llvm-worktrees/llvm-project/lldb/test/API/dotest.py", line 8, in <module>

    raise Exception("Found multiple tests with the name %s" % name)
