No idea this can possibly have worked recently.

Closes: #15416

Otherwise it seems like we are talking about upgrading from 3.2 to 3.5.

within a paragraph that is about both automatic and manual upgrades.

I'm pretty sure it'll break the ISO build.

I wouldn't have used an inline if the content was meant to be used only
twice, but we should reuse it at least for the 3.6.1 release notes and
probably for 3.7 as well.

The goal is to avoid issues such as #15400: Jenkins had been telling us for
48 hours that the testing branch did not build reproducibly anymore,
but the release manager missed that, built a tentative 3.6 ISO and decided
to release it as-is.
