Make tests deterministic by providing unique timestamps (elastic#93350)

The threat intel data that we are loading for these tests was previously
copy/pasted, resulting in all docs having the same @timestamp value.
This resulted in nondeterministic ordering which manifested as test
failures.

This fixes the issue by giving a unique timestamp to each indicator
document, and then unskips/updates tests according to this new ordering.
