metamask-mobile feat: Improve localization workflow such that it allows for branch/PR focused translation

This allows for branch/PR focused translations

Description

Currently, translation only happens once changes to the en.json file are merged to main. These changes could include new keys being added or changes to english text. What this means is that there is no way currently to require that translations be in place before the feature goes live. It could make it through translation before being released but there is currently no way to require that we wait for translations.

Manual testing steps

Use case 1 (feature branch requires translation):

Developer creates a branch for feature which requires translations
They add keys or change english source and when they are ready for translations to be done they create a PR and add the label “ready-for-translation”
Manually trigger crowdin-branch-pr-ready-for-translation.yml ON THE BRANCH
Confirm branch created in crowdin with just the untranslated keys (plus any untranslated ones from main or any translated but not merged keys from main) - This is where we could get confusion on the BLEND side.
Wait for translations (Desi will likely have to talk to BLEND to let them know what we are doing and get these translations done so that we can finish out the test)
Manually trigger the translation check before translations complete (confirm no translation PR created)
Manually trigger the translation check after translations complete (confirm PR created off this branch)
Merge translation PR into branch, manually remove label (later PR will do this automatically), manually delete localization branch for this branch (later PR will do this automatically)
Merge PR for feature to main
Manually trigger crowdin-upload-both-sources-translations.yml and ensure translations show on main in crowdin.
Manually trigger crowdin-branch-cleanup.yml and make sure the branch is removed from crowdin

Use Case 2 (main branch translations):

Developer is working just normally and adds new keys or changes english version in some way.
They go through normal PR flow once they merge to main
Manually trigger crowdin-upload-both-sources-translations.yml
Confirm new keys are on main
Work with Blend to get one thing translated so we can see crowdin-pull-branch-pr-completed-translations.yml pull down the partial translation
Manually trigger crowdin-pull-branch-pr-completed-translations.yml and check the localization PR has the translations.
