[heft-jest-plugin] Migrate from @types/heft-jest to @types/jest (#5772)

* [heft-jest-plugin] Migrate from @types/heft-jest to @types/jest

Replace the custom @types/heft-jest type shim with the official @types/jest
package across all projects. Also removes the jest-global-setup.ts workaround
that injected mocked() as a global — Jest 30 ships jest.mocked() as the
standard API, so the global shim is no longer appropriate.
