Invalid configuration is generated for Angular frontend when running with --rc

[maciekbartczak]

The .manifest file in the angular template contains different entries for beforeDevCommand depending on the target:

beforeDevCommand = {% pkg_manager_run_command %} start

...

[mobile]
beforeDevCommand = {% pkg_manager_run_command %} start {% double_dash_with_space %}--host $HOST --public-host $HOST

However in #748 the differentiation between mobile and non mobile target was removed, which in result makes the generated tauri.conf.json always contain the mobile version of the beforeDevCommand.
This behaviour in my understanding is incorrect, since it requires the HOST environment variable to be set, and running the desktop target using pnpm tauri dev does not set the HOST variable which results in errors during app startup (tauri-apps/tauri#10737).
When the beforeDevCommand in tauri.conf.json is manually set to the regular (non-mobile) version everything works flawlessly.
