This week's renovate update (#40897) tried and failed to upgrade google/go-github because of how this module's major version is included in the module import path.

Automated major upgrades for this module were supposed to be disabled by #40326, but that PR did not actually work as expected as it configured github.com/google/go-github in matchPackageNames which only does an exact module name match and does not match the actual module name which includes the module major version.

This PR fixes the logic by configuring this matchPackageNames with a glob pattern.

Relevant renovate documentations on exact string matches, glob patterns and regex in matchPackageNames: https://docs.renovatebot.com/string-pattern-matching/

Note: for a followup, instead of disabling major upgrades for this module, we could consider instead configuring renovate with a postUpgradeTasks to sed the module import string to use the new major version.
