[Bug] i18n messages files fix

[flx-sta]

Tip

pagefaultgames/pokerogue-locales#21

Why am I making these changes?

So apparently Pontoon has this special behavior where it expects any files containing the word messages to have a specific kind of json pattern.

So instead of adapting to that I just decided to rename those files. Since we don't want to change their namespaces i had to add them to namespace->file matcher.

What are the changes from a developer perspective?

Make sure that the namespaces for *messages get matched to the correctly renamed files

How to test the changes?

Run the game
see if the renamed files are loaded properly so no i18n strings are missing.
