Return original command error in error tree

[lpusok]

Shove the original command error in the error tree. This allows checking for the specific exit code by code like this:

	var exitError *exec.ExitError
	if errors.As(err, &exitError) {

wrapError did not do this, breaking code expecting the above to work. This is fixed by using a feature in go 1.20 that allows wrapping multiple errors. (https://tip.golang.org/doc/go1.20#errors)

Output on go >= 1.20:

Run: failed to shutdown Simulator, command execution failed: command failed with exit status 149 (xcrun "simctl" "shutdown" "216F1ECE-9545-4CDD-A706-199C432EA348"): check the command's output for details 

Output on go < 1.20:

Run: failed to shutdown Simulator, command execution failed: command failed with exit status 149 (xcrun "simctl" "shutdown" "D519202A-FCD1-496C-AFCC-134697A128C8"): check the command's output for details %!w(*errorutil.HiddenOriginalError=&{0x140000e67a0})
