Add Standards back to Security topics

[loopiezlol]

Although we can't merge it yet as the content consumer won't know how to parse standards, we should make a PR, re-adding them to all insights in Security topic.

As mentioned here https://github.com/enkidevs/curriculum/pull/485, I've removed them such we can go forward with the topic launch.

If you checkout at f71f12edee10bd4cbc749fd5f8c385ebaa7cd666 you can see the insight files, having the standards field. They can be copy-pasted from here. I wouldn't recommend a revert commit, as in the same commit I applied more fixes.
