[Optimization] Minify json files in build directory (after beta rebase)

[flx-sta]

VITE UPDATE (v4 => v5)

Also updated by #3213 but much cleaner

I had to bump vite up to v5 due to this issue
vitejs/vite#15714

Otherwise typedoc would have failed constantly.

Why does typedoc suddenly fail?
Because I'm using node types inside my self-written json-minify plugin. To be exact the filesystem fs type. vite is "copying" those types but since node v18++ those copied type are out of date. The vite team hasn't migrated that fix into v4 yet and there is no indicator to do that yet.

Duplicate of #3073

What are the changes?

it minifies all the json files in the given directorties (currently /dist/images and /dist/battle-anim). That way we can work with the beautified jsons but the users retrieve the minified ones.

Why am I doing these changes?

Reduce file-size load

What did change?

Added the minifyJson plugin to the vite.config.
