Should we bump to 43 instead? 44 launched as beta a couple weeks ago and the full release is scheduled to happen in a couple of weeks, 42 will go out of support shortly after that.

Alternatively, we could look at something more stable like CentOS Stream 10, which should fairly new packages.

I considered 42 as the minimal shift needed to get go 1.25, but yeah, if it will go out of support soon, let's switch to 43.

We might want to update the title of the PR. I made a small comment, but I think it's fine.

[nit] I was wondering about the -y flag at the end of the command instead of after install as we usually do.

Looking at the documentation, it looks like the expected location of -y is right after dnf ([GLOBAL OPTIONS]). So we never do it right... It works that way, so it's probably fine.
