Incorrect return type for ActiveRecord encrypted hashes

[olivier-thatch]

Bit of an edge case, but:

class MyModel < ApplicationRecord
  serialize :secret_hash, type:Hash, coder: JSON
  encrypts :secret_hash
end

results in the following signatures:

class MyModel
    sig { returns(::String) }
    def secret_hash; end

    sig { params(value: ::String).returns(::String) }
    def secret_hash=(value); end
end

which makes sense since secret_hash is a string in the DB schema (due to being encrypted), but the type for the accessors should be T::Hash[T.untyped, T.untyped].

I can take a stab at a PR if this is something that would be accepted into Tapioca.

Yeah T::Hash[T.untyped, T.untyped] looks more correct
