Enable OCSP Stapling

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/1058

We may try to capture such calls and return a friendlier response (HTML
or JSON) saying "The Synapse Admin API is not enabled", but that may not

we have now.

Hi,
After discussion with Slavi ([link to private chat](https://matrix.to/#/!GWNJzoHiCybWdouIiP:etke.cc/$_XpK8-ucbWvxY667IVZ9ROZPqSVkG2UGglNagrbDQmw?via=etke.cc&via=devture.com)), we agreed on adding services that use matrix-docker-ansible-deploy as a core to list in README file.

@GoMatrixHosting could you approve the description is correct, please? (Sorry, I just put what I know about your service)

Upgrade Synapse (1.33.1 -> 1.33.2)

689dcea773 wasn't enough. The `upstream/..` tags are
