Refactor some functions.
Try to fetch functions from github api just once when vrct started.(It used to every time plugin tab has opened so easy to reach to the api limit)
@emotion/react, @emotion/styled: It was installed when installed MUI (Material UI) as official install documentation but it doesn't use it for now.
@typescript-eslint/eslint-plugin, @typescript-eslint/parser: It's not using Typescript so remove it. I think it was installed when it set up by vite at the first time? I guess.
[bugfix] Note: I think this is tauri's bug. When I try to resize the window and hovered dragable area, I could see resize cursor but it work as a dragging the window behavior that should't be.
Updated npm packages but still not work so I managed it as adding margin-top by referring Discord title bar.
I didn't want to use it because it's hard to customize. but I didn't like the slider's thumbs behaver so I did it.
It has Tooltip component so It will be useful somewhere. still difficult to customize it, tho.
