Adds missing translation for french language

[orobardet]

Some strings were missing in the french translation, this PR adds them.

The npm run build removed the file material/overrides/assets/javascripts/iconsearch_index.json and added a \n at the end of material/.icons/material/LICENSE.
Since it does not seems to have any relation to the new translations, I did not commit these changes.

But I can if needed.

Thanks!

Those changes don't belong here, that's correct. The icon index is only built when the twemoji database is found in the venv folder, which obviously isn't there on your installation:

mkdocs-material/tools/build/index.ts

Lines 250 to 261 in ec4de0d

	const emojis$ = defer(() => resolve("venv/**/twemoji_db.py"))
	.pipe(
	switchMap(file => read(file)),
	map(data => {
	const [, payload] = data.match(/^emoji = ({.*})$.alias/ms)!
	return Object.entries<TwemojiIcon>(JSON.parse(payload))
	.reduce((index, [name, { unicode }]) => index.set(
	name.replace(/(^:|:$)/g, ""),
	`${unicode}.svg`
	), new Map<string, string>())
	})
	)

It's specific to Material for MkDocs' own site, and is not necessary for the distribution. TL;DR: nevermind.
