It's unclear to me what "post msrv snapshot tests" are. If we raise the msrv should this change?

Yes. We have three brackets of tests
- tests that work on the msrv, stable and nightly
- tests that work on stable and nightly
- tests that work on nightly only
Regarding 2: The default defmt features support the msrv, but some of the optional features require a newer version, e.g. ip_in_core. These tests are the ones in POST_MSRV_TESTS. Maybe OPTIONAL_FEATURE_TESTS is better?
Regarding 3: These tests use unstable features.

So POST_MSRV means "any version above our MSRV"? If so, a little comment would be really nice:
// Tests which run on all Rustc versions later than our MSRV
const POST_MSRV_SNAPSHOT_TESTS: &[&str] = &["net"];

Well it's not all versions. It's some version in MSRV..=STABLE.

This PR documents and tests Rust 1.76 as our MSRV. This is the version Ferrocene 24.05 is based on. Before we only guaranteed to support the latest stable.
I tried to store the MSRV in an env variable in the workflow file, but unfortunately env variables are not available in the strategy matrix, so it has to be repeated.
