Update cast ABI Commands part (outdated and missing decode-XXX commands)

[Hugoo]

Following this PR: foundry-rs/foundry#9413

which renamed decoding functions to: decode-XXX

The CLI reference is ok:

https://book.getfoundry.sh/reference/cli/cast/decode-abi

But the "cast ABI Commands" part is outdated and missing some functions (cast decode-error, etc.)

Maybe creating a "Decoding" section could also make sense.
