Version API

This API returns the running Synapse version. This is useful when a Synapse instance is behind a proxy that does not forward the 'Server' header (which also contains Synapse version information).

The api is:

GET /_synapse/admin/v1/server_version

It returns a JSON body like the following:

{
    "server_version": "0.99.2rc1 (b=develop, abcdef123)"
}

Changed in Synapse 1.94.0: The python_version key was removed from the response body.
