Improve some French localizations

[dan-jac]

This PR adresses some issues with the French localization of Edit. Specifically:

• The Edit menu previously got translated to "Éditer", which does not match convention. In French, these menu titles are not traditionally in verb form; they're nouns. So Edit is usually translated to "Édition", which is what I've done here.
• The existing string for "Focus statusbar" ("Focus sur la barre d'état") isn't great. This is a command, so it should be a verb in its infinitive form. That could be "focuser", but that's not really a French word; it's an anglicism that's been Frenchified a bit. I've changed this to "Activer", which matches convention and sounds natural.
• There was inconsistency in the use of the "straight apostrophe" ' vs. the "true apostrophe" ’. I've updated the strings to consistently use the true apostrophe.
• In French, there should be a space (non-breaking) before characters like question marks and colons. I've added these in, to match Microsoft's French style guide and other Microsoft apps.

I completely trust you on this. I'm not a native speaker and these were all machine translated. Thank you for doing this!

(The alternative is using Microsoft internal translation services, but this would've required me to use their services exclusively and reject your PR. I didn't want that.)
