Project doesn't build anymore on newer compiler versions

We're getting:

error: opaque type's hidden type cannot be another opaque type from the same scope
  --> bootloader/src/main.rs:34:1
   |
34 | #[embassy::main]
   | ^^^^^^^^^^^^^^^^ one of the two opaque types used here has to be outside its defining scope
   |
note: opaque type whose hidden type is being assigned
  --> bootloader/src/main.rs:34:1
   |
34 | #[embassy::main]
   | ^^^^^^^^^^^^^^^^
note: opaque type being used as hidden type
  --> bootloader/src/main.rs:34:1
   |
34 | #[embassy::main]
   | ^^^^^^^^^^^^^^^^
   = note: this error originates in the attribute macro `::embassy::task` (in Nightly builds, run with -Z macro-backtrace for more info)

Probably need to update to a newer version of Embassy
