Code validation warnings when Groovy GString is inside Script tag (HTML and GSP)

**Example**
```

$(function () {
if (${profile?.length() ?: 0} != 0) {
// do something
}
}

```
And code reformat breaks proper code style.

Start by reproducing the example in the issue in both HTML and GSP, checking the validation warnings and code reformatting around the Groovy GString inside the script tag. Done means the example no longer produces incorrect validation warnings and reformatting preserves the intended code style.
