pgAdmin 4 commit: Upgraded the jQuery-contextMenu to v2.1.0 (latest sta

Upgraded the jQuery-contextMenu to v2.1.0 (latest stable version) in
order to fix the issue rendering the context menu for longer text.

Needs to do some modification in the existing pgAdmin4 CSS theme to make
it looks like/near the existing look and feel.
