3.0.0.RC1 - f:all - Invalid markup is being generated for numeric fields. Commas are added to type number.

I have created a very basic grails 4.0.0.RC1 app to demonstrate the problem:

https://github.com/codeconsole/grailsnumberbug

```
package numberbug

class Bug {

int num = 123456789

static constraints = {
}
}
```

``

creates an input field
``

which is not valid markup in either Chrome or Safari.

The default behavior should be to not put commas in numbers due to the fact it breaks everything
