[Docs] `v0.11.dev0` still appears in the docs

[leandron]

I've noticed that we still have v0.11.dev0 being shown in the documentation page at https://tvm.apache.org/docs/.

@areusch @driazati do you know how to make that to be updated to v0.12.dev0, which would be where we are now?

It looks like https://tvm.apache.org/docs/contribute/release_process.html#update-tvm-version-on-main still needs to happen (i'm seeing some v0.11.0s around e.g. in conda/recipe/meta.yaml)
