Add tests for markups in image descriptions

Those cases are actually covered in the 'commonmark-spec' test suite.
However, those tests use non-existent images so they are not checked for
rendered images. As such, in this commit we add a new case in
'samples/images.md', primarily to test markups in descriptions of
rendered images.
