feat: added localisation for eggs and french translations

[TeKrop]

Added localisation support for eggs (list and gacha). Also added french translation. Tested in both English and French. Italian, Spanish and German translations are copied from English.

Here are a few changes which could be discussed if needed :

• Gacha types french descriptions (for french native speakers or translators)
• Pull options text refactoring, in order to facilitate changes
• Pull options text resizing to make the french translation visually OK (see following screenshots)

I see sevral changes to make :

• Switching all apostrophes from ' to ’
• Each time a Pokémon Egg is mentioned, it should be written with the first letter in capital, so "Œuf"
• Missing spaces before some exclamation marks in some sentences
• For the sentence "Qu'est-ce qui va en sortir ? Ça va mettre du temps." in the image, adding a non-breaking space between "sortir" and the question mark, to avoid it to be left alone.

@Adri1 Thank you for your feedbacks 🙏 I made the fixes you mentionned, and will make more tests before putting the PR as ready for review 👍

I made #841 in portuguese without noticing this. Looks good to me
