11:52 AM Ruby Bug #21541: make install is failing due to using rdoc repo

I think the best solution is to make sure `rdoc` always commit the generated files with CI checks verifying that they're up to date. ~~`prism`,~~ `rbs`, and `debug` (tho it's for readme) already do this and I don't see much issues cause... st0012 (Stan Lo)

09:31 AM Ruby Misc #21367: Remove link to ruby-doc.org from www.ruby-lang.org/en/documentation/
