Merge branch 'update-browser-gem' into 'master'

Update browser gem to 2.2.0 A user with a certain browser would hit an Error 500: ``` ArgumentError: invalid value for Float(): "0." from browser/accept_language.rb:45:in `Float' from browser/accept_language.rb:45:in `quality' from browser/accept_language.rb:15:in `each' from browser/accept_language.rb:15:in `sort_by' from browser/accept_language.rb:15:in `parse' from browser/base.rb:13:in `initialize' from browser.rb:125:in `new' from browser.rb:125:in `block in new' from browser.rb:125:in `map' from browser.rb:125:in `new' from browser/action_controller.rb:15:in `browser' from abstract_controller/helpers.rb:67:in `browser' from app/views/layouts/_head.html.haml:38:in `_app_views_layouts__head_html_haml__1626593241142487258_59224880' ``` The root cause when the `Accept-Language` header would contain a float for the quality value (e.g. en-GB,en;q=0.v5).
