test(oxlint): test two real rules with same name but from different plugins (#8821)

Related to #8814 

This test case is designed to verify that two different rules, having
the same name but coming from different plugins, are treated as distinct
rules rather than simple aliases.

In `unicorn`, there is only one rule, `no-negated-condition`, which is
aliased to `eslint`.
