[RN] Implement suggestions for "JSF" section

fjuma1@redhat.com has provided feedback during review of the "JSF" section of the release notes that the "Mojarra/MyFaces 2.2.x" section should be completely removed. There are additional requested changes to the Configuration guide that have been captured in JBEAP-13520. The full feedback can also be seen in that JIRA.

----------------------------
I took a look at Section "3.15. JSF" in the release notes. It looks good except for the "Mojarra/MyFaces 2.2.x" section. This section currently mentions that "<module name="org.jboss.as.jsf"/>" should be added to the dependencies in the jsf-injection module. Instead of mentioning this in the release notes, I think it makes more sense to specify this in the Configuration Guide in Section 7.9.1 "Installing a JSF Implementation".

...

With the above change, the "Mojarra/MyFaces 2.2.x" section in the release notes can just be removed since the example templates already include "<module name="org.jboss.as.jsf"/>" in the dependencies.
