Warning message on plugin installation even after private plugin

[Hitoshi Ozawa，修改在11 年前。]

Plugin installation was removed in 6.1.1 but it became available once again by installing Private Plugin portlet. This is all very good but there's still a message about it going to be replaced with MarketPlace. Would appreciate if Liferay.com will include in a hook to delete this message because it is annoying and users would ask about it.

This may just be a problem with the community patched version.

If I can clone the branch, I may create a pull-request to get this resolved. I still can't clone the portal - keeps timing out.

EDIT: Seems to be in the Private Plugin portlet.
