Fix lifecycle hook function types

[villasv]

Summary

Fixes #10066

Test plan

Added a new type test suite for the @jest/globals to ensure lifecycle hooks are not typed as HookFn that could return Promise, but are at least functions that return void.

Ideally this'd include type tests (based on #10407), but we don't have any tests for these globals, so possibly out of scope?

[villasv]

Added a new test file for the globals. The test successfully fails™ before the suggested changes, but is now passing.

It doesn't test exactly what I wanted (I wanted to test the argument types, it's testing the function return types), but it does the job.

Wonderful, thanks! Could you update the changelog as well?

Wasn't sure where to put it, left it on the master's Fixes section.
