Shorten run command descriptions

[scottkurz]

Our UI plugin.xml has commands like:

      <command
            id="io.openliberty.tools.eclipse.launch.run.tests.shortcut.run"
            name="Liberty Run Tests"
            description="Launches a request to run the tests provided by the associated project"
            categoryId="org.eclipse.debug.ui.category.run">
      </command>

Though I can't remember how :) there is a view in which this description pops up as help / info display.

The description : "Launches a request to run the tests provided by the associated project" is overly long in this view; it doesn't fit. It'd be better as simply: "Run the project tests".

And similarly for all the commands.
