Review French navigation file

Hi @olivierthiffault

@NSoiffer noticed that the French translation was missing the file `navigate.yaml.` The rules in this file control the speech when you are navigating inside expressions.

Neil has made a French `navigate.yaml` in the French folder in the main branch, but it needs to be checked. Would you have the time to do this, possible before Friday? It would be great to have the file checked before the release, but it's understandable if you don't have the time :)

The following words are translated and need to be checked:

The words after `t:`

In the rule `say-command` the words after `Prefix`.

In the rule `into-or-out-of-mtr`, the word after the equal sign in the match statement: `match: "$Move2D = 'dans'"`("dans" is the translation of "in")

There are many instances of the structure:
French: `Move2D: "'dans'"`
English: `Move2D: "'in'"`

There are many instances of the structure:
French: `Move2D:"'hors de'"`
English: `Move2D: "'out of'"`

There are some instances of the structure:
English: `Move2D: "'end of'"`
French: `Move2D: "'fin de'"`

There are some instances of the structure:
French: `Move2D: "'début de'"`
English: `Move2D: "'start of'"`

Open the French navigate.yaml in the French folder on the main branch and review the entries after t:, Prefix in say-command, and the Move2D translations in the named rules. Compare the French wording with the English examples and verify that dans, hors de, fin de, and début de are used consistently. Done means the file's listed translations have been checked and any needed corrections are committed.
