During the verification of JBEAP-15966, I realized that there is not used non-breakable space between product name and its version. This can result in a situation where product name is placed on the end of one line and appropriate version continues on a new line, e.g.:

identifier assigned to an HTTP session has changed between JBoss EAP 6.4 and JBoss EAP
7.

After looking in the doc sources, it looks like non-breakable space is used only on a few places for these cases.

I believe we should use non-breakable space between product name and its version so these two values are not separated on different lines.
