[v7.0/forgejo] Improvements to English locale (#4459)
**Backport:** https://codeberg.org/forgejo/forgejo/pulls/4453
A few fixes and improvements.
Notable changes:
- `issues.ref_closing_from` now makes sense.
https://codeberg.org/attachments/c091cc42-f0bf-4a14-8e43-8c66ead5ef06
- `pulls.cmd_instruction_hint`: removed full stop.
https://codeberg.org/attachments/41fcf979-3a5b-48f8-9e60-bde0b06dd522
- `settings.wiki_rename_branch_main_desc`: fix based on change in stalled 3546 so the sentence makes sense.
- `find_file.go_to_file`: better describe what the button does
https://codeberg.org/attachments/e181e486-3376-446d-a994-bfe65c125a70
- `repos.unadopted.no_more`: it's also shown when there are no results, not when the server "ran out of results"
https://codeberg.org/attachments/9077cbc4-f9e7-4ee5-ad86-6cfff41fec37
- `security.txt`: rephrase to decrease brokenness of English.
- `translation_meta`: added a special string, can be used to trigger Weblate to create a PR, which is usable for debugging
