Group otel dependency updates into single PRs

[jhrozek]

Summary

We had issues where we pushed an update of a single otel library without
updating the rest. This should make sure we update them in lockstep.

Change Type

• Bug fix (resolves an issue without affecting existing features)
• Feature (adds new functionality without breaking changes)
• Breaking change (may impact existing functionalities or require documentation updates)
• Documentation (updates or additions to documentation)
• Refactoring or test improvements (no bug fixes or new functionality)

Testing

N/A but hopefully we get a PR soon as we are behind the otel versions

Review Checklist:

• Reviewed my own code for quality and clarity.
• Added comments to complex or tricky code sections.
• Updated any affected documentation.
• Included tests that validate the fix or feature.
• Checked that related changes are merged.
