Update documentation in quick install chapter with 'navigate dashboard.<your base domain>:443"

[eisenhaus335]

This request seems funny and probably common sense. But i ask it anyway. Could the documentation put this word? I was struggling connecting to my server domain with "dashboard.domain.net" and checking why i cant access it. The documentation does show to do docker logs netmaker and it shows Fatal: Admin: could not connect to broker, token timeout, exiting .... So i follow the github issue. I am unable to reach my dashboard.domain.net. Then i just realized that https is usually an 443 port and not 80. I tried it with "dashboard.doman.net:443" and it works. My browser does erase the 443 word due to browser stuff, showing "dashboard.domain.net"
