We are switching our translations platform from Transifex to Weblate.
Hence, we are using a new config file to sync our translations between
GitHub and Weblate.
This commit makes the config file a hidden file by default.
The `.tx/config` file will be deleted in a later commit when the
Transifex sync is shut down.
