Add list of tags on the news section

[yersan]

It would be nice to have a list of Tags available on the right side of the news section. Somehow, there is one already, the one that filters out release announcements, this has been implemented as a clickable button.

A list of tags would be useful so you can just go directly to the related information you are looking for, these tags could be extracted from the news metadata.

As inspiration, see column Tags on the Elytron blog: https://wildfly-security.github.io/wildfly-elytron/blog/
