chore(lint): disabled rules that dont apply to this project (#2408)

the performance and readability of reduce is not a concern in this project since maintainers are
familiar with the idiom and are iterating over small lists. the filter rule is disabled selectively
since the filter being identified is not Array.filter

closes #2403
