x/pkgsite: versions in pkg.go.dev not up-to-date for pkg.go.dev/github.com/projectcalico/calico

[frozenprocess]

Hi,
It seems like the go package version for https://pkg.go.dev/github.com/projectcalico/calico is outdated.
Last update seems to be from 2019

The module doesn't follow the versioning requirements of major version suffixes for go modules.
