[release/6.0] Don't run the JIT formatting job in CI

[BruceForstall]

The format job depends on the main branch of dotnet/jitutils (which isn't
properly versioned). Avoid future changes to jitutils causing a break in
servicing by disabling the formatting job.

Note that there is very little benefit to maintaining the formatting
CI requirement in servicing anyway.

@dotnet/jit-contrib I propose to disable the JIT formatting job in the release/6.0 branch to prevent possible breaking changes later on, since the job depends on the jitutils main branch. If I get a PR signoff, I'll ask for approval.

I think it makes sense to disable the job for now.

But we also need either finish dotnet/jitutils#219 (since that was my PR - I probably should finish it) or find another way of publishing versioned jitutils artifacts.

Approved. Given this is infra. we just need to coordinate when this can be merged.
