* Fix display of room notification debug info
* Add 'one' string because apprently it just displays nothing at all
if that's missing, rather than erroring or falling back to use the 'other'.
* Simplify and always display the count: it's debug info so it's best to
be very explicit anyway, plus simpler code & one less string.
* Update snapshot
* Make localization keys on HelpUserSettingsTab compatible with agglutinative and/or SOV type languages
* Make localization keys on room notifications debug dialog on devtools compatible with agglutinative and/or SOV type languages
* Make keys compatible with inflection
* Clarify context for Weblate translators
