Supports Jetty Client 12

[st-user]

Context

• We can utilize jetty-client 9, 10 and 11 with 'zerodep-web-push-java'.
• 'zerodep-web-push-java' (optionally) depends on org.eclipse.jetty.client.HttpClient.
• In order for jetty-client 9, 10 and 11 to make HTTP requests, we have to use org.eclipse.jetty.client.api.Request
  • https://javadoc.jetty.org/jetty-11/org/eclipse/jetty/client/HttpClient.html#POST(java.lang.String)
• However in jetty-client 12, we have to use org.eclipse.jetty.client.Request.
  • https://javadoc.jetty.org/jetty-12/org/eclipse/jetty/client/HttpClient.html#POST(java.lang.String)
• Spring Boot 3.2.6 or higher seems to depend on jetty 12 (12.0.9). So we can't use 'zerodep-web-push-java' with jetty-client in Spring Boot 3.2.6 or higher.
