Fix github deprecated warnings

Every CI run we get tons of warnings like:

The `set-output` command is deprecated and will be disabled soon. Please upgrade to using Environment Files.

It looks like actions-rs/toolchain is unmaintained:

actions-rs/toolchain#221

Many projects are switching over to dtolnay/rust-toolchain, let's do
the same.
