Header info didn't have x_token_server

[JonMerlevede]

Expected behavior

When using OAuth authentication and posting an access token that is no longer valid but can be refreshed, the Trino Python client refreshes the token without requiring user interaction.

Actual behavior

When using OAuth authentication and posting an access token that is no longer valid but that can be refreshed, the Trino Python client crashes with the exception:

trino.exceptions.TrinoAuthError: Error: header info didn't have x_token_server

Steps To Reproduce

• Obtain an access token from Trino through the OAuth flow, and let Trino save it to your keyring.
• Wait until the access token expires, but not so long that the token can no longer be refreshed.
• Make another call to Trino.

This issue has also been reported in the trino dbt client: starburstdata/dbt-trino#432.
