opentelemetry-bridge should use the ELASTIC_APM_API_KEY

[itay-ct]

current docs for opentelemetry-bridge example use ELASTIC_APM_SECRET_TOKEN but recent versions prefer ELASTIC_APM_API_KEY otherwise 'unsupported authorization scheme' is raised. Docs/README should be updated.

Hi @itay-ct,
Are you referring to step (2) at https://www.elastic.co/guide/en/apm/agent/nodejs/current/opentelemetry-bridge.html#otel-tracing-api?

Docs/README should be updated.

Oh, or do you mean it feels like time to update all relevant user-guide and getting-started docs to prefer auth using API key rather that secretToken, given API key is the only one that works for both types of cloud-hosted stack?

but recent versions prefer ELASTIC_APM_API_KEY

And by recent versions, do you mean Elastic Cloud Serverless projects? IIUC, those only support API key auth.
