Patch release for 4.2.0 to remove attrdict module dependency wheel install failure

[junwoo091400]

Operating system: Ubuntu 22.04
wxPython version & source: PyPi
Python version & source: Python 3.10.6

Description of the problem:
As described in this issue very well: #2225, current install of wxpython version 4.2.0 (https://pypi.org/project/wxPython/4.2.0/) fails, due to missing dependency to attrdict module, imported here:

Phoenix/buildtools/config.py

Line 30 in b567d1e

from attrdict import AttrDict

Proposed Solution
To me, it seems like cherry picking this commit: 2e9169e, to the 4.2.0 release (https://github.com/wxWidgets/Phoenix/releases/tag/wxPython-4.2.0), and doing a patch release would solve the problem.

Note
However, I am also wondering, since the dependency is needed in buildtools/config.py, wouldn't this dependency fit better in requirements/intall.txt, instead of devel.txt?

E.g. here: 2e9169e#diff-48561a6ac9f59b3b79790238a78d2c345125e61834588671ac55f3fdafe1cd58R24

Even if you ensure attrdict is installed, it is not compatible with python 3.10+ as from collections import Mapping was moved to from collections.abc import Mapping.

Broken here too. Tried uninstalling and installing attrdict. Same for attrdict3. Tried the '--use-pep517' option. I think next I will try a venv with an older python.

Here running Lubuntu 22.10, and Python 3.10.7

DEPRECATION: wxpython is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at pypa/pip#8559

@h00man you snipped the relevant parts of the output. :( When I saw it earlier via email, your error had nothing to do with attrdict. Instead, you're missing some Linux package prerequisites needed to build wxPython. See https://github.com/wxWidgets/Phoenix#prerequisites.

[swt2c]

New release 4.2.1 has been made which removes attrdict as a requirement on Linux.
