Percy exec fails binding to ipv6

[danpowell88]

The problem

Cannot run percy exec

npx @percy/cli exec:start -v

Environment

• Node version: 14.19.1
• @percy/cli version: 1.27.7
• OS version:
• Type of shell command-line [interface]: bash

Details

Running exec on 1.27.7. tries to bind to an ipv6 interface which is not available on this machine and thus fails, revering back to 1.24.4 resolves the issue. I suspect this was introduced with #1463
