Bugs in v2022.12.0

[jim-easterbrook]

I apologise for releasing v2022.12.0 with several bugs that I really should have spotted before release. I've issued the following patch releases:

v2022.12.0.1 fixes
TypeError: descriptor 'tr' requires a 'PySide2.QtCore.QObject' object but received a 'str'
or
TypeError: tr(self, str, disambiguation: str = None, n: int = -1): first argument of unbound method must have type 'QObject'
errors when doing "help -> about Photini" or a map tab search.

v2022.12.0.2 fixes TypeError: can only join an iterable error when writing an XMP "sidecar" file.

v2022.12.0.3 fixes incorrect "LangAlt" values written to IPTC-IIM metadata.
