[FIX]: Examples in the specification results in a HTTP 404

### Specs

DPV

### Errors

Fix the links to examples that results in 404-s.

E.g. Section 17.1.525 Prohibition has an example that links to  https://w3c.github.io/dpv/examples/#E0066

I think all the linked examples in section 17 are not pointing to an existing page
