Describe the bug

Some links generated by forge doc are relative (like ../../../foo), and some are absolute (like /contracts/foo). When hosting documentation generated by forge doc on GitHub pages, the root is something like <user>.github.io/<repo>, and absolute links don't work because they don't have the <repo> part. Relative links works normally.

Steps to reproduce:

• Clone cartesi/rollups-contracts
• Run pnpm i to install all Node.js packages
• Run forge doc -b to build documentation pages
• Run grep -l '<a href="/' -r docs and you'll see there will be several pages with absolute links:
