In the Qt documentation, you can find the enum type the value belongs
to by looking at the class involved and searching for the value:
https://doc.qt.io/qt-6/qaction.html#MenuRole-enum

Thus, that would be QAction.MenuRole.NoRole.

Or you ask PyQt5:

    >>> from PyQt5.QtWidgets import QAction
    >>> type(QAction.NoRole)
    <class 'PyQt5.QtWidgets.QAction.MenuRole'>

However, why bother doing this manually at all? I'm aware of three
different tools to do this automatically.

Mine:
https://github.com/qutebrowser/qutebrowser/blob/qt6-v2/scripts/dev/rewrite_find_enums.py
https://github.com/qutebrowser/qutebrowser/blob/qt6-v2/scripts/dev/rewrite_enums.py
with a list of enum mappings here:
