non proxy hosts tooltip suggests a misleading syntax

If one is to add non proxy hosts - the tooltip (? icon) suggests regular expression \.somecompany\.com. Inserting a host with such format does not produce an error, but while having a wildcard '' at the beginning of a hostname causes an error to show up in the console upon restart of Nexus.
A correct regex patter should be something like:
.+\.somecompany\.com
This correctly validates upon restart.

Acceptance Criteria:

• Change help text to correct pattern
