Broken links

[martin-t]

The docs contain broken links - examples:

• https://rapier.rs/docs/user_guides/rust/colliders/ : "or with contact modification"
• https://rapier.rs/docs/user_guides/rust/advanced_collision_detection/ : "See the rigid-body CCD section for details"

Note these are just 2 examples i ran into, there's probably more (especially since both seem to have the same cause - the relative links should go up first).

Both return 404 so it should be possible to write a periodic CI action to check all links on the website and detect this automatically.

I've found out that the problem is related to the way links are generated.

When you open a documentation page, it adds a trailing slash to the URL. This trailing slash makes relative links broken.

But when you navigate through the documentation via the left panel, it doesn't add trailing slashes, and relative links work fine.

I have found one on this page:
https://rapier.rs/docs/user_guides/bevy_plugin/advanced_collision_detection/#collision-and-contact-force-events

When linking out to advanced_collision_detection#collision-and-contact-force-events it adds an extra folder and becomes this:
https://rapier.rs/docs/user_guides/bevy_plugin/colliders/advanced_collision_detection#collision-and-contact-force-events

When it should be this:
https://rapier.rs/docs/user_guides/bevy_plugin/advanced_collision_detection/#collision-and-contact-force-events

I was going to submit a PR to add the leading slash but actually I think that would simply make the link relative to the root domain, which would also be wrong - not sure if there is a syntax to make it go up one dir first.
