Describe the issue you're reporting

The package https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/pkg/stanza/operator/transformer/copy/ uses the reserved word "copy" as package name, which makes the linter predeclared fail.

1. Remove the exclusion from .golangci.yml by removing those lines:

        predeclared:
    ignore: copy

2. Rename the package so the linter no longer fails.

I'd prefer not to make any change here because it would be breaking. The package is named consistently with other operators and it seems like a simple enough exception to note in the linter config.

Closing as not planned. Please reopen if you feel strongly about this.
