Move Spring Boot Session replication with WebFilter back [DEX-297]

[frant-hartm]

Some code samples were previously moved out into separate repositories. This makes them hard to maintain.

Changes:

• updates to Hazelcast 5.5.0 and Spring Boot 3.4.0
• added hazelcast-wm (previously this sample was using hazelcast-all that is no longer available)
• fixed how thymeleaf access to session id
• improved test

TODO This sample uses hazelcast-wm library. Spring uses the jakarta namespace in the latest version, we updated to jakarta namespace in 5.1-SNAPSHOT.

We need

• update the hazelcast-wm version to 6.0 (updating to jakarta namespace is major breaking change)
• do a release
