Logout button does not logout IDMty session

**Description**: As a user, when I click the logout button on an IDMty session, I only log out of decidim but remain logged in to IDMty. And when I try to log back in, it won't ask me for my IDMty session, because I am already logged in. So if I want to switch users I need to go into IDMty and logout from there.

**What to do**: Whenever I am logged in with IDMty, when I press the logout button I should also hit the keycloak logout endpoint. The end session endpoint is: https://iam.monterrey.gob.mx/realms/GobMty/protocol/openid-connect/logout you can find all endpoints [here](https://iam.monterrey.gob.mx/realms/IDMty/.well-known/openid-configuration)
