More Sorbet typed: strict RuboCops
- Some of these I bumped to `typed: strict`, some of them I added
  intermediary type signatures to some of the methods to make my life
  easier in the (near, hopefully) future.
- Turns out that RuboCop node matchers that end in `?`
  can return `nil` if they don't match anything, not `false`.

module RuboCop
module Cop
module Homebrew
# Enforces the use of `collection.exclude?(obj)`
# over `!collection.include?(obj)`.
#
# NOTE: This cop is unsafe because false positives will occur for
# receiver objects that do not have an `#exclude?` method (e.g. `IPAddr`).
#
# ### Example
#
# ```ruby
# # bad
# !array.include?(2)
# !hash.include?(:key)
#
# # good
# array.exclude?(2)
# hash.exclude?(:key)
# ```
