Translation: categories are not translated on episodes page

[xthiago]

Describe the bug

Categories name should be translated on episodes page (detail or category listing).

To Reproduce Steps to reproduce the behavior:

1. Go to any podcast page (e.g. https://podverse.fm/pt-BR/episode/py_HRI630) or filter podcasts by category (e.g. https://podverse.fm/pt-BR/podcasts?category=sports) in a language different of English.
2. See error

Expected behavior

The categories present on podverse-web translation should be translated (e.g. Sports to Esportes in Brazilian Portuguese).

Additional context

I will open a PR soon.
