Fix formatter spacing for JSON path operators (->, ->>)

- Treat `->` and `->>` as SQL operators in the lexer.
- Prevent formatter from inserting spaces around JSON path operators.
- Add formatter test for JSON path access.

For example:

```sql
SELECT
    details->'$."first_name"'
FROM
    users;
```
