Why have you made this change?

I dded the -- here to ensure robustness. It explicitly tells tee to stop processing arguments as options, treating $TMP_DIR/test.results strictly as a file name, even if it happens to start with a hyphen.

This can be simplified

This can all be removed in favour of updating/extending https://github.com/please-build/go-rules/blob/master/build_defs/go.build_defs#L1750 - please check if that testing.testBinary definition is still relevant

The upstream already has a expect_output_contains parameter which we shouldn't shadow. You're also introducing a second meaning of the term "output", which is going to be confusing. At a minimum I think the new parameter should be expected_plz_command_output, but I think it'd be nicer to support asserting on stdout and stderr independently, rather than capturing both in one file (at which point expect_stdout_contains and expect_stderr_contains are nice unambiguous names)
command > >(tee stdout.log) 2> >(tee stderr.log >&2) might work here, but you'll need to test that it preserves the exit code correctly. tee is a nice utility for duplicating stdin to a file. See https://stackoverflow.com/a/692407 for more explanation.
Either way, I think you should implement this as part of the upstream rule in https://github.com/please-build/plugin-integration-testing/blob/master/build_defs/e2e.build_defs so that other plugins can benefit from this change.
aside: can you spot the bug in https://github.com/please-build/plugin-integration-testing/blob/master/build_defs/e2e.build_defs#L89
