Merge #244

244: Update MSRV to 1.66; fix detection in CI r=Bromeon a=Bromeon

The unit-test job accidentally used the nightly compiler in MSRV check. Now, `minimal-deps` and `msrv` are two separate jobs.

MSRV 1.63 was incorrect -- two features require newer Rust versions:

1. discriminants on enums with fields (for `*Notification` types)

2. let-else
