eldoc documentation is incomplete in go-mode

[edkolev]

The go language server returns
func(a ...interface{}) (n int, err error),
but the eldoc message which is displayed is
func(a ...interface{})

The issue is probably caused by this replace-regexp-in-string here https://github.com/joaotavora/eglot/blob/master/eglot.el#L1491

To reproduce, run

(eglot--sig-info [(:label "func(a ...interface{}) (n int, err error)" :documentation "Println formats using the default formats for its operands and writes to standard output.
Spaces are always added between operands and a newline is appended.
It returns the number of bytes written and any write error encountered.
" :parameters [(:label "a []interface{}")])] 0 0)

Or to reproduce in a .go file - place the cursor on Println:

package main

import (
	"fmt"
)

func Hello(name string) string {
	return "Hello, " + name
}

func Main() {
	fmt.Println(Hello("World"))
}

This was fixed in #128.

Awesome, thanks!
