[sql install] Set all front menu modules to display sub menus per default when installing Joomla

[infograf768]

Pull Request for Issue #15094

Summary of Changes

As title says.
When creating a frontend menu module the default is to show the sub menus.

				<field
					name="showAllChildren"
					type="radio"
					label="MOD_MENU_FIELD_ALLCHILDREN_LABEL"
					description="MOD_MENU_FIELD_ALLCHILDREN_DESC"
					class="btn-group btn-group-yesno"
					default="1"
					>
					<option value="1">JYES</option>
					<option value="0">JNO</option>
				</field>

This normalises this setting in all sample data.
I see no unwanted consequences: when no submenus available, no change.

Testing Instructions

Patch an instance of Joomla and install with various sample data
This can also be tested using this pack

@infograf768 installed your zip but don't get how to test.

see its an complete install. Test now.

[infograf768]

It's indeed mostly code review, but you can check if none or any sample data installs ok, and then look at the menu modules to confirm that Sub Menu Items parameter is set to Yes.
