Edkrepo fails to install with Python3.11 about edk2-edkrepo

[ndhaller]

I ran some tests with various python installers. Only encountering problem with Python 3.11 on my system.

Base case:
On Windows 11 with Python 3.8.10 installed.
Build C:\git\edk2-edkrepo\dist\EdkRepoSetup-3.1.0.0.exe with Python 3.8.10
Install edkrepo 3.1.0 through EdkRepoSetup-3.1.0.0.exe
Uninstalled Python 3.8.10 using python-3.8.10-amd64.exe

Test 0: Fail (readme issue)
Attempt to install with no python installed.
"Error: Python version 3.8.8 or later is required to run EdkRepo. Please install it before continuing."
edk2-edkrepo readme shows "Python 3.5 or later" as Pre-Requisites, not "3.8.8".
readme needs to update python version requirement.

Python 3.11 deprecated inspect.getargspec()
https://docs.python.org/3.11/library/inspect.html

Python 3.8 and Python 3.9 and Python 3.10 and Python 3.11 support getfullargspec() as "usually a drop-in replacement" for getargspec().
https://docs.python.org/3.8/library/inspect.html
https://docs.python.org/3.9/library/inspect.html
https://docs.python.org/3.10/library/inspect.html
https://docs.python.org/3.11/library/inspect.html

Replacing both instances of getargspec() with getfullargspec(), and the EdkRepoSetup-3.1.0.0.exe installer can be built and run on Windows 11 with python-3.11.1-amd64.exe

With those two line changes, not seeing any other initial problems with using Python 3.11

Test python 3.11.1:
Install python-3.11.1-amd64.exe with default installation settings
py -3 -m pip install wheel
cd build-scripts
build_windows_installer.bat
cd ../dist
Install edkrepo 3.1.0 through EdkRepoSetup-3.1.0.0.exe
Installation Successful
run some test commands:
edkrepo manifest
edkrepo clone
edkrepo status
edkrepo combo
edkrepo checkout
edkrepo sync -u
python 3.11.1 basic functional tests pass

Confirmed, the Windows installer does not support Python 3.7.9. It is a hard installer failure, not optional:

Test python 3.7.9: fail
Install python-3.7.9-amd64.exe with default installation settings
Install edkrepo 3.1.0 through EdkRepoSetup-3.1.0.0.exe
Installation Failed:
"""
Found Python 3.7.9
Error: Python version 3.8.8 or later is required to run EdkRepo. Please install it before continuing.
