Half of this iso longer relevant since 2022a toolchains are deprecated since foss/2025b was defined, see also https://docs.easybuild.io/policies/toolchains/.

@Flamefire If you think it's worth it, can you update this to only touch the 2022b easyconfig?

[Flamefire]

This doesn't introduce any new ECs, can we just merge it even though it does a minor change to an already existing, but deprecated EC?

foss/2022b is now also deprecated as a toolchain.
