Compilation error trying to upgrade to esp-hal 0.20.0

[yanshay]

I tried to upgrade an app I'm working on to esp-hal 0.20 released today and I receive multiple compilation errors as below (exactly the same, just on different lines, replicated many times), what's causing that?

To provide the full picture,
I also updated all other esp-* crates as well as embassy (I assumed it would be compatible with current embassy crates).
I also updated my local copy of mbed-tls to use esp-hal 0.20.0.

    = note: this error originates in the macro `core::include_str` which comes from the expansion of the macro `crate::before_snippet` (in Nightly builds, run with -Z macro-backtrace for more info)

Yea there is a fix coming for that #2040

This has now been resolved in the v0.20.1 release, sorry for the inconvenience!
