Remove locale check

[hschne]

I have a client project where we have this configuration:

I18n.available_locales = [ :de ]

# Set default locale to something other than :en
I18n.default_locale = :de

Notice, there's no :en there. Opening /litestream in this project results in an error .

I18n::InvalidLocale (:en is not a valid locale):
i18n (1.14.7) lib/i18n.rb:382:in `enforce_available_locales!'

Removing enforce_available_locales! fixes the issue (as does adding :en to the list of available locales, of course).

Now, I'm not sure what the reasoning was behind initially enforcing the English locale. None of the views contain localized strings (as far as I can tell?) so forcing a locale doesn't seem to have any impact 🤔
