Regression: SQL parser became less tolerant to columns that match SQL keywords

### Describe the bug

Latest release (between `49.0.2` and `50.0.0`) seems to introduce a regression in SQL parser that causes it to be less tolerant of column names that collide with SQL keywords like `limit` and `offset`.

### To Reproduce

Using `datafusion-cli`:
```sql
> create or replace table x as (
select 1 as offset
);

> select * from x;
+--------+
| offset |
+--------+
| 1 |
+--------+

-- NOTE: Disambiguates correctly
> select offset from x;
+--------+
| offset |
+--------+
| 1 |
+--------+

-- NOTE: Adding a literal in the front breaks disambiguation
> select 'a' as a, offset from x;
🤔 Invalid statement: SQL error: ParserError("Expected: end of statement, found: x at Line: 1, Column: 30")

-- NOTE: Adding a literal in the back - does not!
> select offset, 'a' as a from x;
+--------+---+
| offset | a |
+--------+---+
| 1 | a |
+--------+---+
1 row(s) fetched.

-- NOTE: Quoting helps, but is unfortunate
> select 'a' as a, "offset" from x;
+---+--------+
| a | offset |
+---+--------+
| a | 1 |
+---+--------+
1 row(s) fetched.
```

In Datafusion `49.0.2` disambiguation works fine in all cases, so it's a regression.

Same behaviour reproduces for other keywords like `limit`.

### Expected behavior

SQL and its many dialects are rich with keywords, so context-aware parsing really helps to keep queries free of excessive quoting.

It so happens that `offset` column is present in *hundreds* of our datasets, so if this behavior change is highly impactful and I hope can be reversed.

### Additional context

The cause might be in `sqlparser` crate (between versions `0.55.0` and `0.58.0`). Will attempt to isolate the issue there and create a linked ticket.

Reproduziere die Abfragen in datafusion-cli, insbesondere die Fälle mit einem Literal vor einer Spalte unter Verwendung von offset und limit, und vergleiche das Verhalten mit DataFusion 49.0.2. Untersuche die mögliche Änderung an der sqlparser-Crate zwischen den Versionen 0.55.0 und 0.58.0; abgeschlossen ist die Aufgabe, wenn Spalten mit als Schlüsselwörter benannten Namen korrekt geparst werden, ohne Anführungszeichen zu erfordern, auch wenn ihnen ein Literal vorausgeht.
