feat(lang): Compatibility system for translation function

[GLWine]

Since EDMC version 5.11.0, a new translation method has been introduced to improve localization handling and avoid compatibility issues.

To ensure backward compatibility, it may be useful to introduce a version check mechanism that dynamically selects the most appropriate translation function based on the appversion.

Below is a proof of concept that could be included in https://github.com/aussig/BGS-Tally/blob/develop/bgstally/utils.py. The goal is to assess feasibility and highlight any edge cases or issues before considering production use:

import functools
import semantic_version
import l10n

# Determine the application version and select the appropriate translation method

# Up until version 5.0.0-beta1, appversion is a string.
if isinstance(appversion, str):
    core_version = semantic_version.Version(appversion)
# From 5.0.0-beta1 onwards, appversion is a function returning semantic_version.Version.
elif callable(appversion):
    core_version = appversion()

# Use the appropriate translation method depending on the version
if core_version >= semantic_version.Version('5.11.0'):
    # New translation method (from 5.11.0 onwards)
    _ = functools.partial(l10n.translations.tl, context=__file__)
else:
    # Legacy translation method (up to 5.10.x)
    _ = functools.partial(l10n.Translations.translate, context=__file__)
