[Improvement]: Don't pull in axum 0.6 when trying shuttle-axum feature 'axum-0-7'

[TClasen-Foxit]

Describe the improvement

updating a project to use axum 0.7, using shuttle-axum = { version = "0.35.0", default-features = false, features = ["axum-0-7"], optional = false }, unfortunately still adds axum 0.6 through the transitive shuttle-runtime and its own shuttle-common dependency. I couldn't find a way to disable this by disabling default and optional features on common/runtime.

I looked into it and it looks like this cannot be avoided at the moment as axum seems to be a necessary dependency of shuttle-common itself. I guess this will be fixed once shuttle has been itself updated to axum 0.7

@TClasen-Foxit That's correct. Thanks for raising the concern.
Even after we upgrade to 0.7 we would still need hyperium/tonic#1583 (and maybe some more). A waiting game :)
