Might need updates for newer API

[Schwad]

Monzo::Pot.all
/Users/schwad/.gem/ruby/3.2.2/gems/monzo-0.3.0/lib/monzo/pot.rb:33:in `all': undefined method `map' for nil:NilClass (NoMethodError)

      parsed_response[:pots].map do |item|

Account::All works, but it returns a very large list.

Would love a Ruby-flavored wrapper for the current API, but appreciate it can be hard work to keep up. Just figured I'd file an issue while trialing out the gem.
