HTML builder produces links to absolute paths for JS- and CSS-files

[holmboe]

Describe the bug

The HTML builder uses absolute paths to the JS- and CSS-file.

For whatever reason RTD actually resolves the absolute paths. However in my own tests an absolute path to <script src="/home/MYUSER/.local/pipx/venvs/sphinx/lib/python3.11/site-packages/sphinxcontrib/icon/node_modules/@fortawesome/fontawesome-free/js/all.min.js?v=ec35c6c9"></script> is not found by the webserver.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://sphinx-icon.readthedocs.io/en/latest/quickstart.html
2. View source
3. Observe <script src="/home/docs/checkouts/readthedocs.org/user_builds/sphinx-icon/envs/latest/lib/python3.10/site-packages/sphinxcontrib/icon/node_modules/@fortawesome/fontawesome-free/js/all.min.js?v=ec35c6c9"></script> in the source code.

Expected behavior

Relative paths that the webserver can locate and serve.
