Docs fail to build, without the docs feature enabled.

[Frostie314159]

Bug description

When generating the docs for any crate, that has esp-hal in the dep-tree, the build fails while documenting esp-hal/src/twai/mod.rs, since embedded-can is only included when the unstable feature is enabled.

To Reproduce

1. Generate a new crate and point esp-hal to the main branch
2. Run cargo doc

Expected behavior

Docs don't fail.

Environment

• Any chip

[bugadani]

Please use cargo xtask build-documentation --chips <your chip> --packages esp-hal. Also please note that the whole crate is being overhauled in a major way in this development cycle, where things may or may not work at all before we release it. Breakages like this are expected to happen, especially considering we've barely begun marking APIs unstable.

Thanks for the quick response, that resolves the question.
