Create a daily CI job that compiles against the latest rust-sdk and create an issue if broken

[richvdh]

We keep discovering that the wasm bindings don't build against the current rust SDK. We would like a CI job which runs daily and builds and tests the wasm-bindings against the current rust SDK. If it fails, it should open an issue (if one is not already open), and ping us in a Matrix room.

https://github.com/element-hq/synapse/blob/develop/.github/workflows/twisted_trunk.yml may provide inspiration for the "open an issue" part.
