Update README.md so signal.tube link works on IOS

Should read. https://signal.tube#<your_host_name> not https://signal.tube/#<your_host_name>

the "/" breaks the link on IOS

Issue with the link in the read me. It fails to work on IOS becaues of extra "/"

https://signal.tube#<your_host_name> not https://signal.tube/#<your_host_name>

the "/" breaks the link on IOS

signal.tube links with a / before the fragment should work fine in ios. I've tested this and things seem to to be in order now, but let us know if you are still seeing an issue.
