As of Id345e933, we fire the language change hook when the user switches
language by clicking on a link in the languages list. In order to
compare the user switching language in the scenario above with the user
switching language via the CLS and/or Vector's language switcher, ensure
that we fire language change hook in all treatments.

hook with the $trigger parameter as context for clients to be able to

Following on from Icc64044d, we fire the

opened (and not only the first time that the triggering element is
clicked).

This allows us to correctly instrument (via the
UniversalLanguageSelector instrument) this action so interaction rates
between treatments can be compared.

Per T275894, Readers Web intend to increase the scope of the
UniversalLanguageSelector instrument to help them understand how
users are interacting with the Languages list in sidebar.
In order to keep the UniversalLanguageSelector extension focussed and
not overly Wikimedia-specific, it was agreed that the instrument would
be migrated to the WikimediaEvents extension, where other such
instruments are located.
Therefore, remove all code related to the UniversalLanguageSelector
instrument.
