Fix math min/max signatures (#9830)

Browse source 
# Description
Under the hood those are just `Value::partial_cmp` and this is defined
for all values and defines a partial order over `any`

Should address part of https://github.com/nushell/nushell/issues/9813

# User-Facing Changes
Reenable all behavior before `0.83`

# Tests + Formatting
Added an example to `math min` showing this cursedness
