l10n: Change text string

[Valdnet]

There is a text string that starts with a lowercase letter in the user status settings:

Which is common to other text strings. For the user status settings, it should be matched to other text strings starting with a capital letter or the code should be changed so that it is displayed as "1 hour".

[joshtrichards]

This string is generated by an upstream dependency (moment.js), but maybe we could tweak it via https://github.com/nextcloud/nextcloud-moment and/or https://github.com/nextcloud/nextcloud-vue

It's not something that can be done in server as long as we're using that dependency. Might be worth shifting this over to https://github.com/nextcloud/nextcloud-moment or https://github.com/nextcloud/nextcloud-vue

Maybe NcDateTime could be used: https://github.com/nextcloud/nextcloud-vue/pull/4219
