Standardize OIDC Team Configuration

### Current Behavior

When configuring OIDC, you pass two environment variables for GROUPS
alpine.oidc.team.synchronization
alpine.oidc.teams.claim

one is team, one is team**s**

I was so confused why my groups weren't working until I noticed the difference as I had them both "teams"

### Proposed Behavior

Standardize both to teams or team.
