Broken and missing Javadoc for some build items on https://quarkus.io/guides/all-builditems

Describe the bug

Since the build item javadoc is effectively our SPI to extension authors, and since it's all published at https://quarkus.io/guides/all-builditems, we want it to be complete and informative, and not have weird formatting defects where content stops in the middle of a sentence because links aren't displayed.

We had a big improvement to our javadoc @nderwin in https://github.com/quarkusio/quarkus/commit/9713f7fc044e3d5a1a47ea69c171743a6945af64 (yay!). However, I think Nathan focused more on improving the wording of what we already had, rather than filling in blanks or correcting a formatting big. Nathan's improvements are not reflected on the live site yet, but hopefully I didn't duplicate things he's fixed.

Broken javadoc

Often, for these, the source code looks ok, but something is messing up the formatting, usually where we use a link in the javadoc.

io.quarkus.deployment.builditem.nativeimage.ForceNonWeakReflectiveClassBuildItem (everything after creating in

 * {@code ReflectiveClassBuildItem}

is not displayed

-io.quarkus.deployment.builditem.nativeimage.NativeImageAllowIncompleteClasspathAggregateBuildItem

io.quarkus.deployment.builditem.nativeimage.NativeImageResourceBuildItem

io.quarkus.deployment.builditem.nativeimage.ReflectiveHierarchyBuildItem (not terrible, but the list isn't right)
