v0.11.0

• Added a French translation. (Thanks @daniel-g-gagnon!)
• Improved Accept-Language matching: when the user requests an unknown regional variant (e.g. nl-BE), the primary language subtag is now also matched (e.g. nl).
• Improved email address input validation. This primarily affects testing scenarios, where Portier may now reject configuration and input where an email address doesn't contain a top-level domain (e.g.foobar@localhost).
