Support happy 2.1?

[brandonchinn178]

I'm getting a failure

The program 'happy' version >=1.20 && <1.21 || >=2.0.2 && <2.1 is required but the version found at /home/runner/.local/bin/happy is version 2.1.2

Should the bounds be bumped again?

i see happy 2.1.1 marked deprecated and 2.1.2 was released just this last week. i tested 2.1.2 and found it ok. i've bumped the bounds on hackage (happy:happy == 1.20.* || == 2.0.2 || >= 2.1.2 && < 2.2) on ghc-lib-9.8.3.20241022, ghc-lib-9.10.1.20240511 and ghc-lib-parser-9.8.3.20241022, ghc-lib-parser-9.10.1.20240511.
