I'm sure I'm missing context here, but why do we always add the environment variables? Won't this force an upgrade even if the user doesn't want an upgrade to a dev version?

Can you update this error message to reflect the new filename

testserver/testservernode.go line 71 at r1 (raw file):

		wr, err := newFileLogWriter(fmt.Sprintf("%s.%d", ts.stderr, i))
		if err != nil {
			return fmt.Errorf("unable to open file %s: %w", ts.stderr, err)

ditto

no prob - these env vars are new and also not too intuitive. essentially, the behavior is:

• one allows you to upgrade from an official version to a dev version cockroachdb/cockroach#87468
• one allows you to upgrade from a dev version to an official version cockroachdb/cockroach#90002

so they're just about what's allowed -- it doesn't actually force any upgrades

it's probably better for me to make a more general way of passing in env vars though. i'll do that instead.

i got rid of this change since it's unrelated to this PR and doesn't actually help with what i was trying to get it to do
