Some javascript and css gets blocked by ublock

Hi,
Some javascript and css gets blocked by ublock.

https://github.com/alhassy/org-special-block-extras/assets/43095157/422ff78a-6f9c-44c5-8fa8-f785c70cc764

## I suspect the issue is at https://github.com/alhassy/org-special-block-extras/blob/18d754d8491aa41104a309c3161576bee15e42f6/org-special-block-extras.el#L168

This can be solved by having these embedded or letting the user chose where they're loaded from or having them loaded from a relative path. Or some better solution I can't think of?

## Please tick the following, by replacing `[ ]` with `[X]`

1. [X] I have checked some boxes without reading them.

Edit: I also noticed that these are inserted to document more than once (30 times):

Edit2: This repeated insertion probably should be a seperate issue i guess. It can be seen at documentation page too:
