Remove SSO service account usage for bots

[nahuelverdugo]

Is your feature request related to a problem? Please describe.
The possibility of using an SSO service account for the authentication configuration of a bot supposes an extra configuration that generates more complications than advantages for the user.

For this reason, using the JWT token as the only possible authentication configuration would simplify the problems we have encountered so far:

• Error when deploying workflows
• Documentation maintenance
• Waste of time configuring

Describe the solution you'd like
