Translation Manager 17.10.0 and 18.4.0 released

Translation Manager: link updater fixes for separate-tree sets (Issues#108). Multi URL Picker links were never remapped (an inverted check), and rich text links were missed because Umbraco 17 stores the RTE markup json-escaped inside its value. Both now map to the related page on the target site
Translation Manager: the link updater logs each link it maps and why it leaves one unchanged, and has its first unit tests
Translation Manager: bundled DeepL connector moved to 17.4.0; merged the Test SDK and vite dependabot PRs
Released Jumoo.TranslationManager 17.10.0 to NuGet and @jumoo/translate@17.10.0 to npm (latest-17), with public release notes
Translation Manager: forward-ported v17/main into v18/main (24 commits), moving v18 to Jumoo.Processing 18.3.0 so the background job fixes land in full. Merged with a merge commit
Released Jumoo.TranslationManager 18.4.0 to NuGet and @jumoo/translate@18.4.0 to npm (latest), with public release notes
