Site Editor Templates: Translations strings ignore user settings

[hanneslsm]

Description

The global site language of one of my site is German.
My user has english as its default language.
The template names are translated to German, even though I'd expect it to be english.

Step-by-step reproduction instructions

1. Change the site language to any language, e.g. German
2. Change the language of the user settings to another language, e.g. english
3. See two languages mixed in the site editor > templates

I tested this issue. I reproduced it with the code from the trunk branch.

I tested it with the site settings set to English and the user settings set to Japanese.
In that case, the site editor's "templates" started with a mix of Japanese and English.

The template names that are translated seem to be only templates added from customTemplates in theme.json of the enabled theme (Twenty Twenty-Three in my environment).

Thanks for testing!

I think the default page template titles are getting translated. Related: #51428
