Incorrect Translation of Time Strings for pt_BR

There is an issue with incorrect translation of time strings in the app store when using a browser set to pt_BR. However, I cannot find the right location to fix it on Transifex.

### Steps to reproduce
1. Open an app store listing, such as https://apps.nextcloud.com/apps/deck, with a browser set to pt_BR
2. Scroll down to the comments
3. It contains the name, the star rating, and a string when the comment was added. For example, "6 meses, 2 semanasatrás".

### Expected behaviour

The string should have a space before "atrás" ("6 meses, 2 semanas atrás")

### Actual behaviour


### Browser

**Browser name:** Firefox

**Browser version:** 137.0.2

**Operating system:** Linux
