Bump golang.org/x/tools to v0.7.0 (as minimum) and make new tag

Hi 🙂

Please, bump golang.org/x/tools to v0.7.0 (as minimum) and make new tag in your repo.

It's important to be consistent with new Go 1.20 golangci-lint. Related to https://github.com/golangci/golangci-lint/issues/3086

Thanks!

P.S. Optionally I recommend

• [ ] to move linter to 1.20 totally (go.mod, CI, etc.)
• [ ] add support of dependabot
