Remove stale references to d3d12 bindings wrapper crate (#6675)

While looking through some recent activity for the D3D12 crate, in
particular a spelling fix for the crates.io link to `d3d12`, I realized
that I completely forgot to remove these references to the now unused
and removed `d3d12` crate in #5956.

 Due to complex dependants, we have two MSRV policies:
 
-- `d3d12`, `naga`, `wgpu-core`, `wgpu-hal`, and `wgpu-types`'s MSRV is **1.76**, but may be lower than the rest of the workspace in the future.
+- `naga`, `wgpu-core`, `wgpu-hal`, and `wgpu-types`'s MSRV is **1.76**, but may be lower than the rest of the workspace in the future.
 - The rest of the workspace has an MSRV of **1.76** as well right now, but may be higher than above listed crates.
 
 It is enforced on CI (in "/.github/workflows/ci.yml") with the `CORE_MSRV` and `REPO_MSRV` variables.
