ASGI and nginx documentation need a few updates

[dhdaines]

The ASGI document should mention that in order to run umap via ASGI, you must install the umap-project[sync] optional dependencies - specifically, redis is required for it to load.

Also perhaps this optional dependency configuration should be called [async]?

Also the suggested configuration for nginx is not quite functional. It should have this change:

- proxy_pass http://umap/;
+ proxy_pass http://unix:/srv/umap/umap.sock:/;

And a link to https://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_pass for more information

It may be useful to note that the map configuration section needs to be at the top level outside a server section. This could link to https://nginx.org/en/docs/http/websocket.html for more information

Also, the systemd unit file should have this fairly obvious change:

-     --uds /srv/umap/uvicorn.sock \
+     --uds /srv/umap/umap.sock \

And it may be useful to note that the file mentioned in EnvironmentFile should be used to set the UMAP_SETTINGS environment variable (and can also be used to set other ones).

I can supply a PR of course!

proxy_pass http://umap/;

This comes from an upstream declaration, see here:

https://docs.umap-project.org/en/stable/deploy/wsgi/#uwsgi

Maybe this should be copied to the asgi page.

• --uds /srv/umap/uvicorn.sock \
  

• --uds /srv/umap/umap.sock \

Thanks!
