Many links from the Introduction are broken

[giacecco]

The top 3 links from https://github.com/International-Data-Spaces-Association/IDS-RAM_4_0/blob/main/documentation/1_Introduction/README.md are broken and take to a 404. The pages actually exist, just the links are broken.

There's an unnecessary "." added to the link in the markdown. Whilst this may work locally on some computers, it won't work on github links.
(e.g. line 1.1 Goals of the International Data Spaces in
https://raw.githubusercontent.com/International-Data-Spaces-Association/IDS-RAM_4_0/refs/heads/main/documentation/1_Introduction/README.md) .
You can remove them manually, in the URL but it would be nicer to just fix the markdown
