Case control and measures pages haven't been updated to use ehrQL

Examples:

I've spoken to Brian and someone in the research team will be able to update this code.

Regarding measures. There are currently two pages covering measures in the documentation.

• the new measures in ehrQL page, filed under ehrQL: https://docs.opensafely.org/ehrql/explanation/measures/
• the old measures in cohort extractor page, filed under "legacy": https://docs.opensafely.org/measures/

Anything under legacy doesn't show up in searches. So the page is harmless and can stay there. As far as I can see there's nothing that needs to be updated for the new measures ehrQL page, so we're done. I don't know which commit(s) fixed this between this issue being opened and now, so I won't link to it.

All that remains for this issue is the case-control docs, which @alexwalkerepi has agreed to take a look at.
