Doc: conflicting schema version recommendation

[candlerb]

Describe the bug
The documentation is inconsistent as to whether new installations should use v10 or v11 schema.

To Reproduce
At https://github.com/grafana/loki/blob/master/docs/architecture.md it says:

The current schema recommendation is the v10 schema.

But in the sample loki configuration at https://github.com/grafana/loki/blob/master/cmd/loki/loki-local-config.yaml it says

schema: v11

Expected behavior
If the current schema recommendation is the v10 schema, then I'd expect the sample config to use the v10 schema too.

Environment:
N/A

Screenshots, Promtail config, or terminal output
N/A

hey @candlerb thanks for bringing this up.

v11 is the recommended schema, would you be interested in a PR to fix the docs?
