fix(ui): hardcode sort options in search syntax hint, improve look (#11381)

Followup to https://codeberg.org/forgejo/forgejo/pulls/9109

Fix issue reported by @mahlzahn that the string was confusing translators and they translated the part that wasn't meant to be translated.
Part of this fix was to replace custom IterWithTr with simple dict iteration to allow for placeholders in strings.
