[ignore] align formatting in XQueryTree.g and XQuery.g

Align the format of each rule to what is used as the defacto
standard in both files.

Very simpe rule on a single line

```
rule: SOME THINGS ;
```

Complex rules

```
complexRule
{ Boolean someVar; }
:
    SOME
    { more java; }
    THINGS
    ;
```
