Missing native hints for TextEncryptorUtils

[nhmarujo]

Describe the bug
When I build a native image with a jks file to use with Spring Cloud Decryption it fails to boot with the following error:

21:26:44.825 [main] ERROR org.springframework.boot.SpringApplication -- Application run failed

Originally I had a different error that was reported and got fixed on the framework itself, but now I get this new different error and I was advised to report it here.

I manage to make the application work if I register the following hint:

hints.reflection()
    .registerTypeIfPresent(classLoader, "org.springframework.security.rsa.crypto.RsaSecretEncryptor", INVOKE_DECLARED_CONSTRUCTORS);

Looks like spring cloud is missing to register some hints. Could you please take a look if that is the case? Thank you

Sample
I patched the original sample I used for spring-projects/spring-framework#30628 and created a new branch on which you can replicate the error I showed previously.

Hi. @nhmarujo. Thanks for reporting the issue and suggesting a fix. I have added the missing hint and verified the solution.
