Hi! I believe this fixes #390.

Hmm. Any ideas on why CI build fails?

`go env GOPATH`/bin/golangci-lint run ./...
level=error msg="Running error: context loading failed: failed to load packages: failed to load with go/packages: err: exit status 1: stderr: go: golang.org/x/tools@v0.1.12 requires\n\tgithub.com/yuin/goldmark@v1.4.13: missing go.sum entry; to add it:\n\tgo mod download github.com/yuin/goldmark\n"

SGTM

@quasilyte could you cut a release with this change? I'd hope this would enable go-critic/ golangci-lint to upgrade accordingly?

[quasilyte]

@andig done.
I'll roll a new gocritic release with updated ruleguard the next day.
I would like to merge a couple of more PRs there that address several 1.18 related issues.
