`ImportFileResolver.resolve_file` should verify if the resolved path is a file

[JCZuurmond]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

ImportFileResolver.resolve_file should verify if the resolved path is a file.

ucx/src/databricks/labs/ucx/source_code/files.py

Lines 163 to 168 in 34b3d86

	def resolve_file(self, path_lookup, path: Path) -> MaybeDependency:
	absolute_path = path_lookup.resolve(path)
	if absolute_path:
	return MaybeDependency(Dependency(self._file_loader, absolute_path), [])
	problem = DependencyProblem("file-not-found", f"File not found: {path.as_posix()}")
	return MaybeDependency(None, [problem])

Currently, if a directory is passed to the FileResolver it is resolved successfully.

Expected Behavior

A directory should not be resolved successfully by ImportFileResolver.resolve_file
