Description

### What happens?

If a column name contains a `'.'` I can't select it with `duckdb.ColumnExpression`. Should `ColumnExpression` not do the escaping for us, so we can just pass the column name?

At least, that's what happens for column names that contains spaces

### To Reproduce

```python
import duckdb

rel = duckdb.sql("""select * from values (1, 2), (3, 4) df(a, "b.a")""")
rel.select(duckdb.ColumnExpression('b.a'))
```
```python-traceback
---------------------------------------------------------------------------
BinderException Traceback (most recent call last)
Cell In[3], line 1
----> 1 rel.select(duckdb.ColumnExpression('b.a'))

BinderException: Binder Error: Referenced table "b" not found!
Candidate tables: "unnamed_relation_0ba05ea8514d33bd"
```
