Fix rare failure condition in FieldSortBuilderTests (elastic#74347)

Under rare randomization conditions, the mininum values used in
FieldSortBuilderTests#testIsBottomSortShardDisjoint can currently be
missintepreted and parsed as years by the date parser that is called deeper down
in DateFieldMapper#isFieldWithinQuery. In practice this cannot happen because
`isBottomSortShardDisjoint` uses the formatted sort values for a date field,
which are string values and don't cause this kind of error. This PR fixes that
in the test setup.

Closes elastic#74142
