unsafeptr analyzer of govet is not reporting errors

[sherif-elmetainy]

Welcome

• Yes, I'm using a binary release within 2 latest major releases. Only such installations are supported.
• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've included all information below (version, config, etc.).
• Yes, I've tried with the standalone linter if available (e.g., gocritic, go vet, etc.). (https://golangci-lint.run/usage/linters/)

Description of the problem

The govet linter is not reporting errors by the unsafeptr analyzer.

When I run

$ go vet

I get

# playground
.\main.go:10:14: possible misuse of unsafe.Pointer

However when I run

$ golangci-lint run

I get nothing in the output.

Version of golangci-lint

$ golangci-lint --version
golangci-lint has version 1.52.2 built with go1.20.2 from da04413a on 2023-03-25T18:11:28Z
