[router]: refactor matchArrayGroupName to be similar to matchGroupName (

#27459)

# Why

`matchArrayGroupName` is similar to `matchGroupName` but its regex was
implemented differently and it returned all groups, not just the first
one

This PR keeps the functionality & regex of `matchArrayGroupName` to be
similar to `matchGroupName`.

This addresses some bugs with `matchArrayGroupName` where it incorrectly
handled `((foo),(bar))`
