Docs build broken

[FoamyGuy]

When I build the docs locally I first got a failure due to _bleio module not found.

I added that to the mock list which got me past that error.

But now the build is failing with this error:

WARNING: autodoc: failed to import module 'adafruit_ble_file_transfer'; the following exception was raised:
Traceback (most recent call last):

 [autodoc.import_object]

Which appears to take issue with these lines:

Adafruit_CircuitPython_BLE_File_Transfer/adafruit_ble_file_transfer.py

Lines 59 to 61 in df30c3c

	properties=Characteristic.WRITE_NO_RESPONSE
	| Characteristic.READ
	| Characteristic.NOTIFY,

Characteristic.WRITE_NO_RESPONSE, Characteristic.READ and Characteristic.NOTIFY are all ints if you follow them to their value, though they do go through some intermediary classes.

In a python 3.12 REPL I am able to bitwise OR the values wtihout issue:

Characteristic.NOTIFY | Characteristic.READ | Characteristic.WRITE_NO_RESPONSE
44

I'm not sure why sphinx / autodoc import is failing to do so.

See what Adafruit_CircuitPython_BLE does in pyproject.toml. I think maybe instead of mocking it, you would add adafruit-blinka-bleio as a dependency?
