style: (Theme) Neon Arcade theme. (@Mystical2090)

Description

I made a theme called "Neon Arcade"
It is inspired by arcade places.
This was made with love and passion, as I loved arcade games and neon signs when I was a kid.
The errors are yellow due to red blending with pink.
In addition, caret is cyan while the main color is pink, so there are two accent colors in the typing area.
Furthermore custom CSS gives each nav item its own accent color.
The background is a deep indigo near black, with lavender for untyped words.
I also compared Grape theme to mine to make sure it is comparable to other themes (To make sure it has good quality), and I think my custom nav icons (CSS) file is pretty niche. Also it uses orange and purple, while mine has that playful cyan and pink look!

I hope everyone enjoys this theme!
