Reminder to update the changelog.

I've resolved merge conflicts and merged dev into this branch. At the same time, I made a few minor updates related to the new structure of the schema reference documentation.

[duncandewhurst]

Many properties of Event still reference definitions for common codelists. The codelists need to be moved to CSV files and the references replaced with titles, descriptions and codelist keywords. I haven't commented on them individually as I think most will be addressed by the resolution of #59 and #91

Before merging, need to run ocdskit schema-strict to add missing validation keywords.

I've merged in the Vulnerability changes, I think this is all now fine, just waiting on the decisions in #59 and #91

[duncandewhurst]

I've made the changes discussed in #91

@duncandewhurst just requesting one final review. Stu and Mattia approved this prior to me merging in the Loss PR so if you're happy you can just merge this in. Once this is done it's just the double check of final things that needs doing.

I fixed a few typos and made one copy edit.
