Unbind application volume adjustment gestures (#17634)

Closes #17272

Summary of the issue:
The application volume adjuster feature introduced in #16591 includes default keyboard gestures that:

1. Conflict with the default gestures used by NVDA Remote; and
2. Don't do anything by default, as the feature is disabled.

Description of user facing changes
These gestures are unbound by default. Users can still bind gestures to these commands from the input gestures dialog.

Description of development approach
Removed the `gesture` argument to the `script` decorator on `GlobalCommands.script_increaseApplicationsVolume`, `GlobalCommands.script_decreaseApplicationsVolume`, and `GlobalCommands.script_toggleApplicationsMute`.

Testing strategy:
Ran NVDA from source. Ensured that the commands were unbound by executing the previous keyboard gestures.
Re-bound the gestures in the input gestures dialog, and ensured they worked as expected.

Known issues with pull request:
None.
