Show only the "Test Passed" message when a test passes (#43795)

This restores the behavior of how `at-test` shows a test pass in Julia
v1.0 - v1.6, reverting the display changes introduced when
storing more info in the `Pass` type in #36879, closes #43794.

 Note that this is not a specific feature of the `≈` but rather a general feature of the `@test` macro: `@test a <op> b key=val` is transformed by the macro into `@test op(a, b, key=val)`. It is, however, particularly useful for `≈` tests.
