Feat: Add systray icon size option (#966)

* Feat: Add systray icon size option

Adds ability to adjust custom icon size for systray module

* Fix: (gjs warning/formating)

Fixes:

- gjs warning: theme parsing error - Not using units is deprecated.
Assuming 'px'. (defaults to rem units 1 by default)

- prettier formatting for MenuCustomIcon JSX element

* Fix: Update default icon size / size type def

Updated default icon size to 1.3rem and added type def to
configuration/modules/config/bar/systray/types.ts

* Fix: supposed to be 1.3em not 1.3rem default size
