fix: failing tests in operation-utilities

[cseas]

Description

These tests were passing on Friday but are now failing checks in every PR.
Need to set jest's system time to that date.

Package downgrade is required because jest-* libraries need to be on the same version for modern fake timers to work.
We can either upgrade jest to v27 or downgrade jest-config to v26. Downgrading is quicker since we're low on bandwidth.

Testing

All tests passing now.

• My changes generate no new warnings
