chore: bump Mockolate to 2.0.0-pre.6

[vbreuss]

Updates the aweXpect.Mockolate integration to align with the newer Mockolate prerelease, reflecting API changes in the Mockolate mock registry surface.

Changes:

• Bump Mockolate dependency from 2.0.0-pre.2 to 2.0.0-pre.6 (central package management).
• Update mock verification constraints to use renamed mock.MockRegistry instead of mock.Registrations for interaction/setup tracking.

---

• Part of Prepare for 2.0 release #78
