fix: authenticationType field saved to database (#33196)

## Description
With the introduction of FromRequest for the create datasource API in
[this](https://github.com/appsmithorg/appsmith/pull/33039) PR, we have
restricted the fields that will be accepted from the client in the
request body. Due to this the `authenticationType` field was not getting
accepted from the client in the create datasource API, which lead to the
failure of airtable queries.

This PR allows the acceptance of `authenticationType` field from the
client.
