MBedOs does not build: updates in python dependences cause pdoc3 conflict

[andy31415]

Problem

Bootstrap started failing today apparently due to pip package updates.

A refetch of dependencies seems to have worked, expect mbedos builds fail due to some pdoc dependencies.

Proposed Solution

Figure out the cause of the error and fix (actual cause unclear).

Error looks like:

I attempted to use a previous pdoc3 build and that failed.

Changing pdoc/__init__.py to say 'name=modue' seems to make compilation work (based on the error claiming it is a str). Unsure what the correct module and values are and where they come from.

see #9271 - we had to disable mbedos since it was the only failing build after a constraints update.
