http3-server is leaking the Jetty logging service to web applications

[cowwoc]

Related to #6112, I see that org.eclipse.jetty.http3:http3-common:jar:11.0.14:compile depends on org.eclipse.jetty.quic:quic-common:jar:11.0.14:compile which depends on org.eclipse.jetty:jetty-slf4j-impl:jar:11.0.14:compile which causes the following problem at runtime:

SLF4J: Class path contains multiple SLF4J providers.
SLF4J: Found provider [org.eclipse.jetty.logging.JettyLoggingServiceProvider@37374a5e]
SLF4J: Found provider [ch.qos.logback.classic.spi.LogbackServiceProvider@4671e53b]
SLF4J: See https://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual provider is of type [org.eclipse.jetty.logging.JettyLoggingServiceProvider@37374a5e]

Unfortunate, for now just setup an exclusion.

The problem isn't in quic-common as it has a <scope>test</scope> dependency.
https://github.com/eclipse/jetty.project/blob/jetty-10.0.14/jetty-quic/quic-common/pom.xml

The problem is coming from http3-common.
https://github.com/eclipse/jetty.project/blob/jetty-10.0.15/jetty-http3/http3-common/pom.xml

Confirmed with a quick dependency:tree on the jetty-10.0.14 tag (also present in jetty-10.0.15 and HEAD)
