legal(license): Set repository spdx from LICENSE

Sets the repository spdx file (in `.repository`) based on the LICENSE.md

This is intended to make it easier to apply licensing stamps on resources through automation. The spdx convention can be applied onto artifacts (like tarballs/docker images/etc), and having them in a commonly accessible location like `.repository/license.spdx` makes it easier for any build automation to take advantage of it.
