[DX] Allow using br tags in translations to avoid confusion

[arielj]

This PR fixes #4377

There were many translations that were not respecting the indexed placeholders from i18next, adding content between br tags that don't support content.

This PR changes a few things:

• I removed all the translations that were wrong
• I updated the ones that were correct to use <br /> instead of <X></X> to avoid confusion in weblate
• I fixed the config of i18next-parser to generate <br /> tags in the english file
• I added a script that we can run to run some checks on the translations, I didn't make this a linter step in the CI actions because I don't know if it's correct the way it's implemented now to make it a block (in some languages maybe it makes sense to skip tags), so for now it's a helper script that we can run before releases for a sanity check
