Note: This is missing and update to take into account the modules added at PR #382

Merging this to proceed with the release

Sorry I didn't get the chance to review this at the time.

The correct fix (using raise QtBindingsNotFoundError from None) we discussed on the issue that solves the two problems I pointed out with the initial naive implementation was not implemented, making the error/traceback message and behavior more appropriate and less confusing, as it is currently treated and printed as an unexpected error during error handling rather than a intentional wrapper error (with raise from), and furthermore prints the error message and traceback from importing pyside6, making users think it was incorrectly trying to use that binding instead of the one they selected.

Here's how the error output looks now:

>>> import qtpy.QtCore
Traceback (most recent call last):
  File "C:\Users\C. A. M. Gerlach\Documents\dev\SpyderDev\qtpy\qtpy\__init__.py", line 252, in <module>
    from PySide6 import __version__ as PYSIDE_VERSION  # analysis:ignore
ModuleNotFoundError: No module named 'PySide6'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\C. A. M. Gerlach\Documents\dev\SpyderDev\qtpy\qtpy\__init__.py", line 259, in <module>
    raise QtBindingsNotFoundError()
qtpy.QtBindingsNotFoundError: No Qt bindings could be found

and here's how it should look with the correct raise QtBindingsNotFoundError from None:

>>> import qtpy.QtCore
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\C. A. M. Gerlach\Documents\dev\SpyderDev\qtpy\qtpy\__init__.py", line 259, in <module>
    raise QtBindingsNotFoundError from None
qtpy.QtBindingsNotFoundError: No Qt bindings could be found

I've opened issue #390 to document this, and PR #391 to fix this.
