Bump OTEL to v0.89.0

Description of the issue

The contrib was bumped to v0.89.0 as part of amazon-contributing/opentelemetry-collector-contrib#141. The agent needs to be updated as well to take in those changes.

This allows us to take in some of the upstream fixes like the pkg/stanza/adapter panic fix.
