test: Fix nock compatibility with fake timers

[Gudahtt]

Description

The nock library is not compatible with the fake timers we use in unit tests because it uses the Node.js timers API. This API is not mocked correctly by the version of Jest we are using.

Jest uses @sinon/fake-timers internally, which didn't support mocking the Node.js timers API until v11.0.0 (see sinonjs/fake-timers#467) This package is updated in Jest as part of the v30 release, which is currently under development.

To workaround this problem in the meantime, the nock package has been updated and patched to use global timers rather than the timers API. Global timers are mocked correctly.
