Test Flight is back: Firefox for iOS beta testing

[Delphine Lebédel]

Hey localizers,

Thanks to Stefan and his team, we can now add more people to these test
builds.

A few people have recently asked me about this, so I want to call-out here
more generally: if you want to test Firefox for iOS localized beta builds,
shoot me an email, telling me which email you want us to add - and the iOS
team can help get that going.

thanks!
Delphine
