[Updates Communication] Push approval criteria update

[Robert McKenna]

Given the level of demand for getting fixes into the jdk11u train the
maintainers have decided to redefine the approval criteria to the
following:

"Any reasonable fix which contributes to the stability, security
 or performance of the affected line should be considered."

I should note that fixes which meet the new criteria are not guaranteed
approval but we certainly intend to approve more changes than we did
under initial criteria with which the JDK Updates Project was set up.

As a result of the change I've approved all pending requests. If you
have an outstanding jdk11u-fix-request please check it for the jdk11u-
fix-yes label and then proceed with your push to the jdk11u forest. [1]

I have updated the project page to reflect the new changes. [2], [3]
