Fix inline links for the site rebuild

Short description

The inline links on the mkdocs rebuild need to be gone through one by one and fixed accordingly.

Such things should exclusively be Markdown syntax: Link description.

Anything else is useless and wastes space and time. This is a great first issue for those wanting to contribute.
I don't know how many of these links exist in the rebuild. I have found 20+ so far.

Research

Markdown syntax described above.
