Add synapse version to /_matrix/static

[mvgorcum]

Currently the easiest way to find your synapse version is arguably through the federation tester, or /_matrix/federation/v1/version, which is not that well documented. Adding the running version to the static page seems like a decent (and easy enough) addition.

Better seems to be /_synapse/admin/v1/server_version, see also PR #6051.

I'd still like to see the version added to the static page.

The 'correct' way to query version is curl http://localhost:8008/_synapse/admin/v1/server_version

You could also add it to _matrix/static though you'd have to dynamically populate the currently static page.

It is still "static", albeit locking it to a version

Thinking about this again, it would seem to be possible to insert git comment + server version into the template at startup? One-time template evaluation, and then store the HTML string into memory.
