chore: add data about previous deployment to posthog events

[chase-crumbaugh]

Adds data about previous deployment to posthog events. This is necessary so that we can alert on if this is a project's first deployment with functions. Very slight downside of this is that it adds an additional query to evolveDeployment to look up information about the previous deployment
