refactor: Use errors package to compare and assert error types

[zyfy29]

close #3699

follows https://go.dev/blog/go1.13-errors to handle error types with errors package

[zyfy29]

Actually I added a lint rule go-errorlint to do it, would you like to add it to this project? If so I could open another pr to do it because I think it's better to leave 2 commit for refactor: and ci:.

That sounds great, thank you, @zyfy29!

Thank you, @zyfy29! I like this much better.
Just a few more questions and suggestions for you, please, then we should be ready for a second LGTM+Approval from any other contributor to this repo before merging since many things have changed from the first review.

Sorry for the mistakes, I found most of them are made by Intellij IDEA's quick-fix and now I've checked it again.
