config: scopes_supported doesn't have offline_access

[sawadashota]

Describe the bug

Document says supported_scope at discovery always has offline_access but actually discovery doesn't have it.
https://www.ory.sh/hydra/docs/reference/configuration

Reproducing the bug

Steps to reproduce the behavior:

1. Run DSN=memory go run main.go serve all
2. Make API Request to with curl -k https://127.0.0.1:4444/.well-known/openid-configuration
3. Response doesn't have offline_access at scopes_supported property

Expected behavior

I'm not sure which way hydra should go.

• Response should have offline_access at scopes_supported property
• Document should be fixed

Environment

• Version: git sha hash 5661ec3
• Environment: Mac

Additional context

DefaultClientScope has offline_access

hydra/driver/configuration/provider_viper.go
