Left over editorial changes to be made in metarSpeci.xsd

[blchoy]

We missed the changes to the documentation in metarSpeci.xsd in 2025-2RC2:

<element nillable="true" name="rvr" minOccurs="0" maxOccurs="unbounded">
	<annotation>
		<documentation>RVR conditions are required if horizontal visibility or RVR is less than 1500 meters, up to a maximum of four runways</documentation>
	</annotation>
	<complexType>
		<complexContent>
			<extension base="iwxxm:AerodromeRunwayVisualRangePropertyType">
				<attribute name="nilReason" type="gml:NilReasonType"/>
			</extension>
		</complexContent>
	</complexType>
</element>

", up to a maximum of four runways" should be removed.

This is fixed in 2025-2.
