Configure index in @ParameterizedTest display names

This commit prepends "[{index}] " to all custom display names
configured via @ParameterizedTest.

This provides better diagnostics between the "technical names" reported
on the CI server vs. the "display names" reported within a developer's
IDE.

See gh-23451
