apache-tomcat cleanup request

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

Anyone with an opinion on apache-tomcat, please take a look. pkgsrc
contains:

www/apache-tomcat55
www/apache-tomcat6
www/apache-tomcat7
www/apache-tomcat8
www/apache-tomcat85
www/apache-tomcat9

If I understand https://tomcat.apache.org/whichversion.html correctly,
only 8.5.x, 9.x, 10.1.x and 11.x are currently supported.

Can someone please clean that up and for extra points, add the newest
supported versions?

Thanks,
 Thomas
