docs: example is added with a server written in Go

[AndrusGerman]

Reason for the proposal:

Because different servers already support golang. I think it's a good idea to add golang as an example.

why gorilla/mux:

Since it complies with the net / http standards of golang. It has no conflicts with the standard library

The code (Golang) has been verified and works correctly.

What exactly did you modify?

These changes only include modifications to the 'history-mode.md' files. Adding the example of a server in Go

Did you implement the example in all languages?

Yes

Notes

I previously created a pull request #2961, but the implementation was not complete and created a new pull request.

This is exactly what I wanted! I tried using this: https://github.com/ddo/go-vue-handler, but your solution works perfectly with gorilla/mux. Thanks a lot for this, wish this gets merged soon.

Checking my pull request list, I see that this has not been confirmed for more than 3 years, I'm willing to update it, but surely the documentation will change with respect to the original pull request.
Everything is fine?
