Remove all []() placeholders

[Dropries]

Change description

This is a large stylistic PR that aims to ensure that the API return proses in a single language. When a prose contains []{a:b}, this pattern is replaced by b, which exists only in English, resulting in sentences mixing foreign languages and a single English word b.

In each data/v2/csv/~_prose.csv file, I replaced all empty square brackets of the form []{a:b} by [c]{a:b} where c is obtained from the data/v2/csv/a_names.csv file based on the local_language_id of the prose.

A few German []{mechanic:b} are still empty because there is no file containing the translation of mechanics and I don't really know German...

hi @Dropries thanks for the PR. If you are willing to help again I'd like to remove all these [](). They were a part of Veekuns data and probably they used that placeholder to link resources internally in their website.

We currently don't have any docs documenting it. It occurs only in some places, so I'd say it's time to remove it. It would be nice to re-do the work you've done by completely removing the placeholder and add only the right language wording.

Then we could also remove the current logic that is now replacing the placeholder. Can you work on this?

Done, there aren't any []{} left !
