Update OpenTelemetry dependencies for collector to v0.98.0

[rapphil]

• Update OpenTelemetry collector dependencies to v0.98.0
• Use go v1.21 since this is a minimal requirement for OpenTelemetry collector components. Add testing for Go 1.22, drop testing for Go 1.20 opentelemetry-collector#9507 . This was causing our dependabot updates to fail silently.
• Use ~ instead of ^ for the go version that should be used while building the collector so that we have fine control over the version used. This is aligned with how the go version is managed in the OpenTelemetry collector.
• Updates APIs that changed from version 0.92.0 to v0.98.0.
