Update ASGI requirements (#911)

* remove `jinja2`

Piccolo has `jinja2` as a direct dependency, so this shouldn't be needed.

* remove `requeste`

I think this was needed for Starlette at some point, but it has since transitioned to `httpx`, so I don't think it's needed any more.

* move `piccolo_admin` to `ROUTER_DEPENDENCIES`

We don't use it for `esmerald` so don't include it by default for all routers.

* no longer omit `piccolo_admin` for `esmerald`

* add `piccolo_admin` to `_esmerald_app.py.jinja`
