table alias without as fails to parse

Hello !

The following valid SQL statement fails to parse:

```sql
select my_alias.value from json_each('{"hello": "world"}') my_alias
```

It should parse the same as the following

```sql
select my_alias.value from json_each('{"hello": "world"}') AS my_alias
```

No source file or test is named in the issue. Start by running the two SQL examples against the parser and trace the FROM-clause table-alias entry point; done means the alias without AS parses successfully and behaves the same as the explicitly introduced alias.
