It looks like I was able to fix it by running rustup toolchain add stable-x86_64-unknown-linux-gnu --profile minimal as shown, though I still have no idea why it was needed.

Glad you were able to solve it👍.

This is a known and solved issue, current crates.io is heavily outdated, this is fixed on main. The issue comes from rustup: there was no suitable toolchain that included miri that could be downloaded. We've solved this kind of issue by specifying --profile minimal now.

There is another unrelated warning here also, that you should probably add a target, and not an entire toolchain, but in our case this is actually what we want. the x86_64-unknown-linux-gnu toolchain is what is mounted into the docker container.

Do note that current main is broken on windows, use #665 to make it not so.
