feat(OAuth2): Updated OAuth2 configuration to align with Spring Security 5 expectations

[rahul-chekuri]

• Replaced the old OAuth2 properties under security.authn.oauth2 with the new spring.security.oauth2.client structure.
• Updated OAuth2 provider settings, including client registration and authorization endpoints.
• Modified commands to reflect the new configuration format.

Old Configuration:

security:
  authn:
    oauth2:
      enabled: true
      client:
        clientId: <client-id>
        clientSecret: <client-secret>
        accessTokenUri: https://www.googleapis.com/oauth2/v4/token
        userAuthorizationUri: https://accounts.google.com/o/oauth2/v2/auth
        scope: profile email
      userInfoRequirements:
        hd: <domain>
      resource:
        userInfoUri: https://www.googleapis.com/oauth2/v3/userinfo
      userInfoMapping:
        email: email
        firstName: given_name
        lastName: family_name
      provider: GOOGLE

Old Command:

hal config security authn oauth2 edit --provider google --client-id some_id --client-secret some_secret --user-info-requirements hd=company.io

New Configuration:

spring:
  security:
    oauth2:
      client:

            client-secret: <client-secret>
            authorization-grant-type: authorization_code
            redirect-uri: "https://<your-domain>/login/oauth2/code/google"
            scope: profile,email,openid
            client-name: google
        provider:
