Ambiguous method call with Grails

For Groovy / Grails:

Good code will be reported with a warning (Method call is ambiguous), or with an error if @CompileStatic is used on the method.

This was originally fixed in this issue but it has re-emerged (see the latest comments on the issue).

The code is:

```groovy
import groovy.transform.CompileStatic

class FooController {
def bar() {
render(test: 'ok')
}

@CompileStatic
def baz() {
render test: 'ok'
}
}
```
Using grails grailsVersion=5.3.6

IntelliJ Ultimate Edition Build #IU-241.14494.240, built on March 28, 202

Reproduce the example in a Grails 5.3.6 project using IntelliJ IDEA Ultimate build #IU-241.14494.240, checking both bar() and the @CompileStatic baz() method. Confirm that render(test: 'ok') is reported as ambiguous and that the static version reports an error; done means the false warning and error no longer appear for this code.
