Wrong footnote on sync.md

[repparw]

https://github.com/tasks/docs/blob/main/docs%2Fsync.md#L28

either original footnote #2 got lost on some commit or this didn't have a footnote

I think that PR is for a page that doesn't exist anymore, or am I misunderstanding the issue?

[repparw]

sorry, I didn't write any PR?
I'm pointing to the synchronization docs. on web interface, there are two checks with a ², which is a footnote about Google tasks, seemingly unrelated to caldav and davx5

Ha oh when you wrote #2 GitHub linked it to a PR, now I understand what you're saying
