feat: add "and" logical operator

[icepuma]

What kind of change does this PR introduce?

- doc: https://postgrest.org/en/stable/references/api/tables_views.html#logical-operators
- hint: couldn't find the documentation if "$foreignTable.and" is supported like "$foreignTable.or"

Hey,
there's two things I added. The and operator and the $foreignTable.and. The and operator is documented at the link I shared. The second operator is "documented" here where children.and= should be the case for the second "operator".
