util/docker: Update Dockerfiles for building the documentation

The doc.coreboot.org container is several years out of date, using the
three year old Alpine 3.8 as the base image along with Sphinx related
pip packages which are even older. Accordingly, update the documentation
related pip packages in the coreboot-jenkins-node container as well.

- Update doc.coreboot.org to Alpine 3.18.3
- Update documentation related pip packages on coreboot-jenkins-node
  and doc.coreboot.org to the latest versions on PyPI
- Update Sphinx to 6.2.1 as the latest version of sphinx_rtd_theme does
  not yet support sphinx >= 7

The updates also noticeably improve performance, dropping documentation
build times from ~75 s down to ~42 s on my system from the Alpine+Python
updates alone, and further down to ~35 s with the rest of the updates.

TEST: The documentation builds and renders properly when built using the
updated container.
