Fails to detect new http routing patterns introduced in go1.22

mingo output:
`go.mod declares version 1.23 but computed minimum is 1.1 `

go1.23 is required for proper functionality .... due to "GET\t/{$}" in http.Handler func

```
package main

import (
"fmt"
"net/http"
)

func main() {
http.HandleFunc("GET\t/{$}", homeHandler)
http.ListenAndServe(":8000", nil)
}

func homeHandler(w http.ResponseWriter, r *http.Request) {
fmt.Fprintln(w, "hello world")
}
```

Reproduce the report with the shown main package and the `GET\t/{$}` pattern, then inspect the Go-version detection associated with `go.mod`. Done means mingo recognizes that this routing pattern requires the reported Go version instead of computing a minimum of 1.1.
