[Rule Suggestion] Type-safe collection rules

[TesteurManiak]

• avoid_first: Prefer type-safe operation firstOrNull
• avoid_last: Prefer type-safe operation lastOrNull
• avoid_single: Prefer type-safe operation singleOrNull
• avoid_element_at: Prefer type-safe operation elementAtOrNull
• avoid_first_where: Prefer type-safe operation firstWhereOrNull

Those methods can be found in the collection package.
