Extend support for OIDC groups when multiple OIDC providers configured
### Summary
We have added support [OIDC groups claim ](https://gitlab.com/gitlab-org/gitlab/-/issues/209898) in 15.10 release. But since the implementation is tied to the name `openid_connect` it doesn't support multiple OIDC providers
### Steps to reproduce
- Configure multiple OIDC providers as referenced in https://gitlab.com/gitlab-org/gitlab/-/merge_requests/117764
- Configure groups claim for the second OIDC provider configuration
### What is the current *bug* behavior?
- `groups` claim configuration is ignored
### What is the expected *correct* behavior?
- `groups` claim configuration shouldn't be ignored even when the configuration name is not exactly `openid_connect`
