Update editors/focuswriter to 1.6.11

Summary

Update editors/focuswriter to 1.6.11
Comes from PR 227142 submitted by maintainer

Please, notice that I just applied the update to the port and not the postexec
icon stuff. After reading PR 226122 it is my understanding that the issue is
not resolved or clarified at the moment so I suppose we should apply the same
criteria: update the port but not the other part. Maintainer should be notified
before committing the partial patch.

Test Plan

• portlint -AC OK
• run test in 11.1 OK
• poudriere builds for {10.3,10.4,11.1}{amd64,i386} and 12 i386 available at:

Please go with the partial patch and discuss the remaining issue further with the maintainer.
