[docs] change ID links in ToC to match goldmark parser behavior (#4223)

Signed-off-by: Nicole Mikołajczyk <git@mkljczk.pl>

# Description

I'm not sure if this should be handled this way, but some of the TOC links don't work on Forgejo due to, I guess, the Markdown parser behavior. This, however, makes them not work on GitHub
