pkgsrc changes:
 - Remove patch-go.mod, version was bumped upstream too

Changes:
1.2.1
=====
Security
--------
  * This fixes the security vulnerability where running gh inside of an
    untrusted directory on Windows could lead to .\git.exe, .\git.bat, or a
    similarly crafted executable in the same directory being run instead of the
    system git command. See GHSA-fqfh-778m-2v32

Fixes
-----
  * issue list: fetch and display all labels instead of just the first three
  * pr view <branch>: allow viewing closed PRs

    '<branch>' on GitHub by visiting: <URL> message generated by git push
  * pr checks: improve error message when no checks are reported
  * repo clone: print friendly error for the required argument
  * release create: print friendly error for the required argument
