3419 alt text in any case

Fixes #3419

[Lakoja]

Regarding the current linter error:

Error: "error_failed_set_caption" is translated here but not found in default locale

That is correct as I removed it.

Should/must I remove it from all others as well?
(Or is that done "automatically" once any translation is updated by a translator?)

Once this is merged, Weblate should send a PR to remove it from everywhere, yes. But I can't merge because lint is complaining 🙄
I could bypass the merge block, but I'd prefer it if you removed it everywhere.

Should be good to go if you resolve the conflicts

Done.

It doesn't seem to be a good idea to remove / change things in other files than the default strings.xml.
That was a lot of work now. And lots of conflicts repeatedly...
