Extract common logic for setting error in parse_short_flags (#10709)

Browse Source 
# Description

Since the `else` clause for the nested branches check for the first
unmatched argument, this PR brings together all the conditions where the
positional argument shape is numeric using the `matches!` keyword. This
also allows us to and (`&&`) the condition with when no short flags are
found unlike the `if let ...` statements. Finally, we can handle any
`unmatched_short_flags` at one place.
