Bazarr auto-update disabled by service launcher

### Is this a new Bug? - [x] I checked that the bug hasn't been reported before ### Package Name Bazarr ### Package Version 1.5.5-19 ### Device Model DS416play ### Device Architecture x86_64 ### Firmware Version DSM 7.3.2-86009 Update 3 ### What happened? I noticed that the bazarr installation doesn't seem to perform auto-updates even if the configuration setting is enabled. It seems like the launcher [uses a flag](https://github.com/SynoCommunity/spksrc/blob/05306fb2517f642475b473e4792ad941dbffa51f/spk/bazarr/src/service-setup.sh#L11) `--no-update` that [disables that functionality](https://github.com/morpheus65535/bazarr/blob/a21300b3e1acf1e9e4f58b051ff9204e24459c45/bazarr/app/get_args.py#L36). Is there a reason for this? For testing I manually edited the service startup script to remove the flag and bazarr seems to self-update properly. ### Reproduction steps 1. Enable automatic updates in Bazarr settings 2. Check releases, new version exists, but no way to trigger task to update ### Install Log ```log n/a ``` ### Service Log ```log n/a ``` ### Other Logs ```log n/a ```
