Closes gh-26121

Update `MavenPublishingConventions` to add a new `mavenOptional` feature
that allows us to declare optional dependencies that are also published
in the generated POM.

This change allows us to include the maven-shade-plugin in the
spring-boot-maven-plugin POM which fixes an issue with Eclipse m2e.
