fix(parity): correct uninstall usage suffix in errcli.go

The cmdUsageSuffix map entry for 'apm uninstall' was missing '[OPTIONS]'.
Python Click 8.x emits:
  Usage: apm uninstall [OPTIONS] PACKAGES...
  Try 'apm uninstall --help' for help.

  Error: No such option: --X

Go was emitting (with the wrong map entry):
  Usage: apm uninstall PACKAGES...
  ...

Fixing the suffix to ' [OPTIONS] PACKAGES...' makes Go's reformatted
stderr match Python exactly, resolving PYTHON_CLI_CONTRACT_STATUS=1
for test_every_python_command_rejects_unknown_option_consistently[uninstall].
