String escaping in SQL files results in broken color highlighting

### Apache NetBeans version

Apache NetBeans 16

### What happened

Backslash escaping is not detected by the color highlighting in SQL Files :


I figure this is a bug because SQL does not produces any error when parsing these files, meaning these are acceptable ways of escaping SQL queries, which is not reflected correctly by the color highlighting

### How to reproduce

Write this SQL il any .sql file open in NetBeans and see the code color break :

```sql
INSERT IGNORE INTO categorie (id, parent_id, nom, content, root, lft, rgt, lvl) VALUES
(1, NULL, 'Test1', 'This won\'t be correctly escaped', 12000, 1, 2, 0),
(2, NULL, "Test2", "This won\'t either", 12001, 1, 2, 0);
```

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

No / Don't know

### Operating System

Ubuntu 22.10

### JDK

OpenJDK 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 by opening a .sql file in NetBeans and entering the provided INSERT statements with backslash-escaped quotes. Start by tracing the SQL syntax-highlighting entry point and compare handling of escaped strings with ordinary quoted strings. Done means escaped quotes no longer break color highlighting.
