BED-4655: Add Authentik to docker-compose.dev.yml

[ALCooper12]

Description

• Add authentik to docker-compose.dev.yml
• Added profiles bh-sso as well as bh-sso-only for just support to quickly spin up authentik and bhe

Motivation and Context

• Ticket: BED-4655

Why is this change required? What problem does it solve?

• This adds authentik - https://github.com/goauthentik/authentik to the dev stack. It provides us with an IDP that supports a variety of SSO protocols so we can locally test and support OIDC / SAML auth flows.

How Has This Been Tested?

• Run just bh-sso Note you have to go to http://authentik.localhost/if/flow/initial-setup/ to register an admin password before you can progress further

Please create a bh-api-sso declaration to launch BH with Authentik via the sso profile. The BH deployment for sso requires a slightly different configuration than the base deployment and we'll want to keep those separate and not interfere with normal development workflows.

I think the only thing needed left is the example vars don't match the docker yml, otherwise LGTM!
