WP Loco Translate workflow

[yannlugrin]

💬 Describe the task

To ease both development and deploy, we need to refactor how we use and deploy translation strings.

Here is how it should work:

1. Locally, we can sync our translations to get new keys from the twig templates
2. Then during deploy, we can generate .mo (impossible to version) and .pot (that disable template sync)
3. Finally, admin can update string translations without being overridden during next deploy

Related to antistatique/holdibat#107

✅ Todo

Steps to achieve the task:

• During deploy execute with gettext installed:

$ msgfmt source.po -o destination.mo # not sure if it's necessary regarding the next step
$ msgfilter -i fr_FR.po -o holdibat.pot true

• Then still during deploy, remove all the commited .po to favour the string in the database

🧞 Expected result

Good DX and DB-first string translations
