(On the understanding that v12 will continue to allow us to use
the sorry-cypress service for balancing test parallelisation.)
Reverts "Update dependency cypress to v13 (#11570)"
This reverts commit 35a6595080.
* Use cypress-terminal-report
This cypress plugin gives nice console logs about what is happening: I hope it
will help us debug mysteriously failing tests.
In its default config, it only logs for failing tests.
* another anti-morgan hack
* Disable collection of `console.debug`
* `ctr:info` is not real
* Minimum hacks required to run cypress tests with dendrite
* Remove wget hack since dendrite containers now have curl
* Add basic dendritedocker plugin & hack into login spec for testing
* Add generic HomeserverInstance interface
* Add env var to configure which homeserver to use
* Remove synapse specific homeserver support api
* Update the rest of the tests to use HomeserverInstance
* Update cypress docs to reference new homeserver abstraction
* Fix formatting issues
* Change dendrite to use main branch container
