[lldb] Rename reverse-continue/TestReverseContinueNotSupported.py (NFC) (#137262)

Rename this test because another test by the same name already exists:
reverse-execution/TestReverseContinueNotSupported.py.

Having multiple tests of the same name breaks running any test with:
`lldb-dotest -p <TestName>`.

This tests reverse continue _commands_, and so the rename adds
"Commands" to the test name (TestReverseContinueCommandNotSupported.py)
