Fixed #24559 -- Made MigrationLoader.load_disk() catch more specific ModuleNotFoundError.

Avoids inspecting the exception message, which is not considered a
stable API and can change across Python versions.

ModuleNotFoundError was introduced in Python 3.6. It is a subclass of
ImportError that is raised when the imported module does not exist. It
is not raised for other errors that can occur during an import. This
exception instance has the property "name" which holds the name of
module that failed to import.
