`solana-verify build` does not play nicely with rust-toolchain.toml of different cargo versions

When using rust-toolchain.toml, one often runs into the following error:

Finished fetching build dependencies
error: Unable to update registry `crates-io`

Caused by:
  attempting to make an HTTP request, but --frozen was specified
Finished building program
Program Solana version: v1.16.20
Docker image Solana version: v1.16.20

This can happen even when the rust-toolchain.toml matches the version in the solana v1.16.20 repository.

note: if you use v1.68.0, it plays nicely because thats the compiler that comes with the installed rust container

Each Dockerfile has a 1-to-1 mapping between the Solana version and rust version in order to keep the number of configs needed under control. I'll do a bit of digging to see if there's an easy way to ignore rust-toolchain.toml. In the interim, it might be best to set the toolchain to correspond with the rust version in the Dockerfile

I'm confused because my rust version is solana v1.17.22 and I'm getting this but the rust-toolchain.toml is channel = "1.73.0" for that release.
