cleanup `@opentelemetry/resource-detector-docker` references

[trentm]

The @opentelemetry/resource-detector-docker package was replaced by @opentelemetry/resource-detector-container in #1181 in 2022. That isn't clear from https://www.npmjs.com/package/@opentelemetry/resource-detector-docker

• The package should be marked deprecated in npm.
• https://github.com/open-telemetry/opentelemetry.io/blob/b6ddba1118d07bc3c8d1d07b293f227686d0290e/content/en/docs/languages/js/resources.md#container-resource-detection currently uses @opentelemetry/resource-detector-docker. It should be updated to use the newer package.

I deprecated it in npm: https://www.npmjs.com/package/@opentelemetry/resource-detector-docker.
Only the docs update is left now.

I can take this one to update the docs.

@pichlermarc can you assign this to me, please?
