🐛 Fix log depth for DelegatingLogSink

[alculquicondor]

Fixes #1737

Adds a depth of 1 to the DelegatingLogSink sink, instead of a global depth to the zapr sink.

This global depth is problematic because it doesn't apply to loggers obtained with WithName or WithValues.

Notes for reviewer

To see this fix in action (and the bug before this fix), go to examples/scratch-env/main.go and set Development mode to false.

It looks like the linter is broken

looks like golangci-lint is too old

[alvaroaleman]

I think it should pass after #1976

@alculquicondor can you rebase? It doesn't look like github actions merges into the base prior to reading the job config, I re-ran the action and it still uses the old golang-ci lint version: https://github.com/kubernetes-sigs/controller-runtime/runs/7795811041?check_suite_focus=true#step:3:16
