Build for 1.7.0 fails with go 1.18

[gblues]

Bug Report

git-team version: 1.7.0
go version: 1.18

failure description

When attempting to install git-team via homebrew, the go build step fails because of outdated dependencies.

expected behaviour description

git-team should install successfully

While installing with --HEAD works, it also brings in other code changes.

proposed workaround:

1. create a new branch off the v1.7.0 commit
2. apply this patch, which fixes the build issues
3. tag the commit with v1.7.1
4. update the homebrew formula to v1.7.1
5. on the main branch, bump the dev version up to 1.7.2-alpha1 or whatever

Thank you for bringing this up @gblues and sorry for the late reply. Will look into this as soon as possible.

This commit should resolve the issue for now and reflect the current state of the project.
