Rename CloudWatch o-tel commands to otel with hidden backward-compat aliases (aws#10228)

Rename the 3 CloudWatch OTel enrichment CLI commands from o-tel to otel
naming, consistent with the OpenTelemetry community convention:
- get-o-tel-enrichment -> get-otel-enrichment
- start-o-tel-enrichment -> start-otel-enrichment
- stop-o-tel-enrichment -> stop-otel-enrichment

The old o-tel names are kept as hidden/undocumented aliases for backward
compatibility.
