Sort the theme list alphabetically

[parsiya]

Is your feature request related to a problem? Please describe.
When I click on Select Themes I see two list of themes (each sorted alphabetically). This means I have to scroll down each list individually to figure out which themes are available.

Describe the solution you'd like
Sort all themes alphabetically, together.

Describe alternatives you've considered
More scrolling.

As you can see in the screenshot below, the first list ends as Vuesion and then second list starts with Arc Dark (Material).

Thanks for the extension. This is great.

Good idea, I should have done this to start with!
