Python Client examples with `key`

[almereyda]

The Python examples in:

• https://terminusdb.org/docs/connect-with-python-client/

and

• https://github.com/terminusdb/terminusdb-docs/blob/main/guides/reference-guides/python-client-reference/gitbook-md/client/Client.md
• https://github.com/terminusdb/terminusdb-docs/blob/main/guides/reference-guides/python-client-reference/terminusdb_client.client.md

either reference a deprecated password setting or don't mention the successor key at all.

• https://terminusdb.org/docs/python/#client-connect

It could be nice to have this detail consistent across implementation and documentation, in so it is more easy to create a working database connection, now that the dashboard is gone.

Authentication in https://terminusdb.org/docs/openapi/ against a local instance works as expected. Where a password is asked during a login the key is correctly set.
