Add RIDs for MIRACLE LINUX 8 and 9

[m10k]

Whenever we build dotnet RPMs for MIRACLE LINUX 8 (formerly Asianux Server 8) we have to
apply patches that add RIDs for MIRACLE LINUX. To streamline the build process, we would
like to add our RIDs to the upstream sources, in the same way CentOS and other RHEL-
derivatives do.

This commit adds the following runtime IDs:

• "miraclelinux"
• "miraclelinux-x64"
• "miraclelinux.8"
• "miraclelinux.8-x64"
• "miraclelinux.9"
• "miraclelinux.9-x64"

seems like you either miss some file @m10k or something else change. The failure is clearly related to your change and something is out of sync.

I have looked at the PRs that added RIDs for other distributions (Alpine 3.14 #55857, Debian 11 #56789, Fedora 36 #57832), and they don't seem any different. Since this PR adds a new distro, not just a new version of an existing distro, are there other files that need to be modified?

[safern]

@m10k you want to add it to this file as well: https://github.com/dotnet/runtime/blob/ec15b53daa184583ef978dfd59e30ca4791e9470/src/libraries/Microsoft.NETCore.Platforms/src/runtimeGroups.props

Here is an example of a new platform addition: ec15b53

@safern Thanks for the feedback! I had already added Miracle Linux to runtimeGroups.props, so that doesn't seem to be the issue. The PR for Rocky Linux introduced some other changes that I don't have in my PR, but they are not necessary for Miracle Linux, because on ML we don't have the minor version in /etc/os-release's VERSION_ID.

As far as I can tell, the issue is that the RID graph needs to be rebuilt (/p:UpdateRuntimeFiles=true needs to be passed), which is is something we also have to do when building dotnet on our buildserver - I don't know how I would do that here though.

[safern]

Ah I see, then you have to run the build with /p:UpdateRuntimeFiles=true and then commit whatever changed into this PR.

Sorry, it took me quite a while to follow up.. I'm not sure but I have the feeling it was the newline at the end of the files that caused the tests to fail.
Either way, there are still some failing tests, but they seem unrelated to this change. Do I see that right?

Also, I took the opportunity to add ML9 as well.

[bartonjs]

Seems OK to me (and CI is happy now). Any other comments, @wfurt?

Awesome, thank you everyone!
