Add expiration of oc share to dav endpoint

[tobiasKaminsky]

Coming from https://github.com/nextcloud/server/issues/15819:

Mobile client use dav propfind to get also share information, so they do not need to do different calls, so expiration property should be added there.

@tobiasKaminsky if it's feasible, yes! Accepted does not mean it will be integrated. But that it fits our roadmap and and make sense ;) If you don't know if it's feasible; then it's a 0. needs triage
