chore: Do not update opentelemetry

[JPeer264]

This disables the creation of dependabot updates for opentelemetry. Based on the image below there was not a real benefit of having this, except noise.

For reference: The reason these are low-value is that bumping OpenTelemetry instrumentations needs to happen in lockstep across the entire codebase and often requires additional hand-tuning to make it work.

I created a PR to add a cursor command to make this a bit easier for us: #18253
