@OpenIdProviderMetadata/jwksURI should accept EL

I tried to use EL in `@OpenIdProviderMetadata/jwksURI`, but it failed due to a failure to resolve the EL in the string.

I think all attributes in @OpenIdProviderMetadata should accept EL.

```java
@OpenIdAuthenticationMechanismDefinition(
providerMetadata = @OpenIdProviderMetadata(
jwksURI = "https://${openIdConfig.domain}/.well-known/jwks.json"
//...
```

Start by tracing how @OpenIdProviderMetadata and its jwksURI value are processed, then follow the existing EL resolution path for annotation configuration. Done means the shown jwksURI expression resolves successfully and the issue’s request for EL support across the provider metadata attributes is addressed.
