fix: add credential deletion configuration

[chance-coleman]

Description

With the addition of WebAuthn Passkeys, there wasn't a way for a user to delete and re-create a passkey attached to their accound. This change allows for that use case.

These changes don't change the existing behavior of core or identity config.

Testing Steps

1. Clone in the uds-core branch git clone https://github.com/defenseunicorns/uds-core.git && cd uds-core && git checkout allow-deleting-a-passkey && cd ../
2. comment out the task clone-core here: https://github.com/defenseunicorns/uds-identity-config/blob/main/tasks.yaml#L117
3. deploy identity config uds run uds-core-integration-tests
4. navigate to sso.uds.dev and register a new user with a passkey
5. in the users account console go to the Account Security -> Signing in page
6. in the Two Factor Authentication section you should see an entry for the passkeys, and notably beside those there should not be a bold red Delete button
7. configure the bundle and disable the registration fields:

            - path: realmAuthFlows
              value:
                USERNAME_PASSWORD_AUTH_ENABLED: true
                X509_AUTH_ENABLED: true
                SOCIAL_AUTH_ENABLED: true
                OTP_ENABLED: false
                WEBAUTHN_ENABLED: true
                X509_MFA_ENABLED: true

8. deploy identity config again uds run uds-core-integration-tests
9. This time register a user with a passkey and verify that there is a big red Delete button next to the passkey
