What version of Ubuntu/glibc does `codspeed-macro` use?

Hi there!

We recently bumped some of uv's runners to ubuntu-24.04 images. However, in doing so, we've encountered a glibc symbol version incompatibility between our builds and the glibc used by the codspeed-macro runner. For example:

https://github.com/astral-sh/uv/actions/runs/21990939547/job/63538462741?pr=16907

This would make sense if codspeed-macro is still based on ubuntu-22.04 (or earlier), but I couldn't find any clear documentation to that effect. We performed that upgrade thinking that it was based on ubuntu-24.04, since the docs for macro runners suggest replacing ubuntu-latest with codspeed-macro (and ubuntu-latest is currently ubuntu-24.04).

Hello!

macro runners are indeed based on ubuntu 22, and you're completely right about the documentation being misleading, we'll fix it. Thanks for the report
