fix: Gracefully handle exceptions during direct i18n loading

If translations.py doesn't exist, MCprep moves to direct i18n, which
directly uses MO files for translations (at the cost of some UI updating
issues). However, if these MO files do not exist, then MCprep will throw
an exception. Since this exception occurs in the creation of
`MCprepEnv`, MCprep is rendered unusable.

This patch adds a basic try-except statement to allow `MCprepEnv` to
handle these exceptions gracefully.
