Lengthen Inner Type short names

[SentryMan]

Change generation to use expanded short name (to avoid name conflicts when inner types have the same name)

public class AuthProvider  {
  @Json
  public record Oauth2Token(
      @Property("expires_in") int expiresIn,
      @Property("access_token") String value,
      @Property("token_type") String tokenType) {}
}

now in the GeneratedJsonComponent class, will generate like this

    builder.add(AuthProvider.Oauth2Token.class, AuthProvider$Oauth2TokenJsonAdapter::new);
