Cannot parse the LEFT JOIN expression

It seems that the join syntax is not supported, here is a simple test

```sql
with t1 as ( select 1 as value ), t2 as ( select 2 as value ) select * from t1 left join t2 on true
```

```
line 0:84 <EOF> or ';' was expected, but got: "join"
with t1 as ( select 1 as value ), t2 as ( select 2 as value ) select * from t1 left join t2 on true
```
