[RC3] font-weight-normal/bolder/lighter tests have a missing image

For RC3 I modified the font-weight-normal/bolder/lighter tests to include an image showing the correct result so that testers could compare their results without also loading the reference page.  But these images did not get copied over by the build scripts:

Tests:
