Fixed audio language chinese

Description

Fix #2614

Chinese language in Bazarr have been replaced with Chinese Simplified they are technically are the same however we separate on the custom languages on Chinese Simplified and Chinese Traditional.

Radarr / Sonarr will send to us Chinese on the audio language and that's totally correct since the 2 types of chinese we separate are for writing only, and that also makes sense to us since we deal with Subtitles.

Since we rely on our languages, and use it to identify the code2 or code3, etc, the Chinese Language becomes orphan, and we are unable to proceed in a few operations that rely on the language code, so we identify it as Chinese Simplified.

As it is quite not correct to display Chinese Simplified as "Audio" since it is only for written, the display is corrected to show as Chinese only instead of Chinese Simplified.

An additional information is that we don't need to manually update the database records to correct it, but users experiencing issues should run or wait to the schedule of the Tasks Sync with Sonarr and Sync with Radarr.
