Improve French translations

[LeMinaw]

Description

As a native French speaker, I fixed a few spelling issues in the current translation.

Motivation and Context

The most important change is replacing Annuler with Rétablir (for Revert), because the first translates to Cancel -which is very misleading, as you moght have guessed.

How Has This Been Tested?

I'm using this fork on a project where it works like expected.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

• I have added my change to CHANGES.rst
  => minor change, I guess it's not required
• All new and existing tests passed.
  => some tests do not pass on my machine, but it's clearly unrelated

I reran and it worked fine.

[ThePumpingLemma]

Why are all of the slashes now backslashes?

[LeMinaw]

Because sadly, path encoding depends on the platform gettext is running on.
I'm not sure whether this is a big deal or not, as running makemessages again on a GNU/Linux system would revert to /.

[ThePumpingLemma]

Would it be worth overriding the makemessages command to normalize the paths? Not sure why Django doesn’t do this by default (AFAIK, Unix-style paths work fine on Windows).

[LeMinaw]

I'm not sure how 3rd-party translation tools manage with this.
Overriding makemessages might be an idea, but it doesn't sound very project-specific to me. I guess Django preserves default gettext behavior, as generally you'll run makemessages on the platform you are translating on before making any edits.

[LeMinaw]

(in the context of this somewhat trivial PR, I'll rather do a quick regex replace and not dive into a makemessages override and the tests that it would need)
