fix example link (#20)

The link redirects to https://pkg.go.dev/github.com/VictoriaMetrics/metrics#example-Counter--Vec , which doesn't exist (note the double `--`: godoc has two slashes, pkg.go.dev only one).

It's maybe a bit weird to link to pkg.go.dev for only one link. I can switch them all over if you prefer. Or they could all go to https://godocs.io instead, which still uses the double `--`: https://godocs.io/github.com/VictoriaMetrics/metrics#example-Counter--Vec
