deps: upgrade github.com/sourcegraph/log
Created by: bobheadxi
This upgrade includes https://github.com/sourcegraph/log/commit/4bb9844c8f2c64e432cd1e62f9993dfb76eb0f1e (https://github.com/sourcegraph/log/pull/28) which is described in https://github.com/sourcegraph/log/pull/24, correctly re-introducing the intended behaviour of panicking if a pre-package-init-logger-initialization is detected in dev environments (first outlined in https://github.com/sourcegraph/sourcegraph/pull/33956).
For a while this would panic when introduced, but issues have been resolved with:
- https://github.com/sourcegraph/sourcegraph/pull/40963
- https://github.com/sourcegraph/sourcegraph/pull/40966
- https://github.com/sourcegraph/sourcegraph/pull/40965 and https://github.com/sourcegraph/log/pull/34
