Description of bug

When passing a numerical value to --state-pruning or --blocks-pruning (like 1000) to polkadot-parachain built from master, it fails with:

error: invalid value '1000' for '--blocks-pruning <PRUNING_MODE>'
[possible values: archive, archive-canonical, <NUMBER>]

Seems to have been broken by: #4810

I added some debug logs here:

polkadot-sdk/substrate/client/cli/src/params/pruning_params.rs

Line 104 in 6daa939

fn from_str(input: &str) -> Result<Self, Self::Err> {

and this function is never called

Steps to reproduce

build polkadot-parachain from latest master
run polkadot-parachain --blocks-pruning 1000
