With SAT-30976 we've moved from NodeJS 18 to 22, but we still list compatibility. That means we run more tests in our CI, wasting time and energy.

Acceptance criteria:

• The removal is announced on Discourse to developers
• Any CI is updated. That means at least https://github.com/theforeman/foreman/blob/develop/.github/matrix.json but perhaps in https://github.com/theforeman/jenkins-jobs there are references.
• Any tooling is updated. At least https://github.com/theforeman/foreman-packaging/blob/fbdd5f46bf492a96fee10d4072ca4b63e735ba3e/.github/workflows/bump_packages.yml#L56
• Packaging requirements are updated (https://github.com/theforeman/foreman-packaging/blob/bbda50cef914e410002687ba958dfc20fa7660f5/packages/foreman/foreman/foreman.spec#L125)
• Developer documentation (https://github.com/theforeman/foreman/tree/develop/developer_docs)
• Legacy installation manual has https://theforeman.org/manuals/nightly/index.html#3.4InstallFromSource (https://github.com/theforeman/theforeman.org)
