Update mocha gem

[fatkodima]

Currently, when trying to run the tests locally, I get

/Users/fatkodima/.asdf/installs/ruby/3.2.2/lib/ruby/gems/3.2.0/gems/mocha-1.7.0/lib/mocha/integration/mini_test/adapter.rb:26:in `included': uninitialized constant MiniTest (NameError)

          Mocha::ExpectationErrorFactory.exception_class = ::MiniTest::Assertion
                                                                     ^^^^^^^^^^^
Did you mean?  Minitest
