getting_started/install_minikube: tsuru command does not work as intended

[mauri870]

I had a 1.21 tsuru client binary downloaded from github releases, upon trying the tsuru login step it failed with:

$ tsuru login
Error: could not call "http://localhost:8080/1.18/auth/schemes", status code: 404

It worked fine when I switched to version 1.17.1.

docs/src/getting_started/install_minikube.md

Lines 80 to 81 in 08b846b

	$ tsuru target-add default http://localhost:8080 -s
	$ tsuru login

Perhaps the helm chart is using an outdated version of the tsuru stack? We could also pin the docs to recomend an older tsuru-client (1.17 seems to work fine).

This line was added 3 months ago, perhaps that fixed the failure.
