chore: delete tests/lean/run/CompilerProbe.lean (#8833)

This test is essentially disabled on `master`, because it prints
nothing. With the new compiler enabled, it prints names of functions
throughout the Lean codebase satisfying certain conditions. Even just
maintaining this on the new compiler branch got old pretty quickly, so I
can't imagine we'd ever want to deal with this on `master`.
