[llvm] [Github][CI] Name Premerge Jobs Experimental (PR #128227)

[Aiden Grossman via llvm-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/128227

As discussed on Discourse (https://discourse.llvm.org/t/googles-plan-for-the-llvm-presubmit-infrastructure/78940/8), this patch renames the premerge jobs to include experimental in them to hopefully better signal that these are still a prototype. This patch does not mark the MacOS job as experimental as that is being used in production on the release branch.
