Describe the bug
Compilation fails when the annotation @log is set on a nested enum.

To Reproduce
Here is an example:

class Example {

  @Log
  enum Status  { OK, KO }
}

The following error appears during compilation:
@Log is not supported on non-static nested classes.

Expected behavior
Should compile without error.
Was working fine in 1.18.20

Version info (please complete the following information):

• Lombok 1.18.22
• all platforms

Additional context
Addind the keyword static to the enum seems to workaround the problem.
