Incorrect auto-indent on Groovy files

### Apache NetBeans version

Apache NetBeans 15 release candidate

### What happened

The auto-indent feature of NetBeans operates incorrectly for Groovy source files.

### How to reproduce

This is a Groovy file. In both examples below, when your cursor is at position "E" and you hit the return key, the cursor should be moved to the position marked as "C". NetBeans puts the cursor in position "I" instead. This formatting bug does not exist in Java.

```
static void meth() {
if (cond)E
I C
}

static void meth2() {
if (cond)
abcdE
C I
}

```

### Did this work correctly in an earlier version?

No / Don't know

### Operating System

Fedora Linux

### JDK

17

### Apache NetBeans packaging

Apache NetBeans provided installer

### Anything else

_No response_

### Are you willing to submit a pull request?

No

### Code of Conduct

Yes

Reproduce the issue in the NetBeans Groovy editor using the two examples in the report, then compare the behavior with Java indentation. Done means pressing Return at each marked E places the cursor at C rather than I in both examples.
