Issue:
adding parametrized queries
many people are already familiar with parametrized queries since they're available in dbt and airflow, so we should add that. possibly with jinja? 

```sql
%%sql --params {"corpus_name": "hamlet", "limit": 10}
SELECT word, SUM(word_count) as count
FROM `bigquery-public-data.samples.shakespeare`
WHERE corpus = {{corpus_name}}
GROUP BY word
ORDER BY count DESC
LIMIT {{limit}}
```

This is how [BigQuery](https://cloud.google.com/python/docs/reference/bigquery/latest/magics) does it (but with a different syntax).


I'm unsure if the `--params {"corpus_name": "hamlet", "limit": 10}` if the best choice. perhaps something simpler like `-p corpus_name hamlet -p limit 10`? similar to what we do in [ploomber-engine](https://ploomber-engine.readthedocs.io/en/latest/user-guide/running.html#parametrizing-notebooks)


Pull request description:
Add parametrized queries
## Describe your changes

### 1. Disable the default IPython var_expand for `{a}, $a` case

We disable the default variable substitution by adding [@no_var_expand](https://ipython.readthedocs.io/en/stable/api/generated/IPython.core.magic.html#IPython.core.magic.no_var_expand) to the line_magic, since we still need to support the default variable substitution + new parametrized fashion in recent versions, we move that parsing part in the `SQLCommand` class

### 2. Add `_var_expand` in `SQLCommand` class

The logic for supporting `{a}, $a` (IPython) + `{{a}}` (new param feature) variable substitution is:

1. Handle the line & cell original string by jinja2 (new param feature)
2. Handle the line & cell original string by IPython var_expand native function to support the IPython way

This execution order matters, since `{a}` is the subset of `{{a}},` we need to handle the `{{a}}` case before being handled by `{a}`

P.S. After those string are parsed, the `:a` part will still be kept, since it's handled by SQLAlchemy engine

### Conclusion

This PR fulfill three requirements:
1. Add @no_var_expand to the execute line magic. We handle the var_expand by ourself
2. When there is variable substitution in `{a}, $a, :a`. We display message (can be discussed)
```
Please aware the variable substition as {a}, $a, and :a format has been deprecated.
Use {{a}} instead.
```
3. Support variable substitution in `{{a}}` fashion, the values will fetch from user name space now

## Preview

## Follow up

We need to support the arg --param & --use-global with {{a}} format in next PR

+# Template
+
+## Variable Expansion as `{{variable}}`
+
+We support the variable expansion in the form of `{{variable}}`, this also allows the user to write the query as template with some dynamic variables
+
+```{code-cell} ipython3
+:tags: [remove-cell]
+
+%load_ext sql
+from pathlib import Path
+from urllib.request import urlretrieve
+
+if not Path("penguins.csv").is_file():
+    urlretrieve(
+        "https://raw.githubusercontent.com/mwaskom/seaborn-data/master/penguins.csv",
+        "penguins.csv",
+    )
+%sql duckdb://
+```
+
+Now, let's give a simple query template and define some variables where we will apply in the template:
+
+```{code-cell} ipython3
+dynamic_limit = 5
+dynamic_column = "island, sex"
+```
+
+```{code-cell} ipython3
+%sql SELECT {{dynamic_column}} FROM penguins.csv LIMIT {{dynamic_limit}}
+```
+
+Note that variables will be fetched from the local namespace into the SQL statement.
+
+Please aware that we also support the `$variable` or `{variable_name}` way, but those will be deprecated in future version, [see more](https://jupysql.ploomber.io/en/latest/intro.html?highlight=variable#variable-substitution).
