Exousia 3 on Tomcat 11

Hi

I'm upgrading from Tomcat 10.1 to Tomcat 11 but o got an NPE during startup:

```
Caused by: java.lang.NullPointerException: Cannot invoke "jakarta.security.auth.message.config.AuthConfigFactory.registerServerAuthModule(jakarta.security.auth.message.module.ServerAuthModule, Object)" because the return value of "jakarta.security.auth.message.config.AuthConfigFactory.getFactory()" is null
at org.glassfish.soteria.servlet.SamRegistrationInstaller.onStartup(SamRegistrationInstaller.java:100)
```

I've found that I have to add the following conf to catalina opts, is it correct?

```
-Djakarta.security.jacc.PolicyConfigurationFactory.provider=org.glassfish.exousia.modules.def.DefaultPolicyConfigurationFactory -Djakarta.security.jacc.policy.provider=org.glassfish.exousia.modules.def.DefaultPolicy
```

this is the relevant part of my `pom.xml`:

```

jakarta.security.enterprise
jakarta.security.enterprise-api
4.0.0

jakarta.authorization
jakarta.authorization-api
3.0.0
provided

org.glassfish.soteria
soteria
4.0.2

com.nimbusds
nimbus-jose-jwt
10.4.2

jakarta.authentication
jakarta.authentication-api
3.1.0
provided

org.glassfish.exousia
exousia
3.0.1

org.glassfish.exousia
exousia.spi.tomcat
3.0.1

```

I've downloaded and placed the following API jars inside `tomcat/lib`:
- jakarta.authorization-api
- jakarta.authentication-api

as a side note:
the Soteria project definition is missing the nimbus-jose-jwt dependecy...
I had to understand which was and include it in my pom
It is an expected behaviour or it's better to open an issure to Soteria?

thanks!!
