This update resolves a dependency conflict that prevented OpenHands from being used alongside langfuse, a popular observability tool. Users can now install and use both OpenHands and langfuse in the same project without dependency conflicts.

Summarize what the PR does, explaining any non-trivial design decisions.
This PR updates the opentelemetry-api dependency from 1.25.0 to ^1.33.1 and protobuf from ^4.21.6,<5.0.0 to ^5.0.0,<6.0.0 to resolve a dependency conflict with langfuse.

The problem was that:

• OpenHands depends on opentelemetry-api 1.25.0
• langfuse depends on opentelemetry-api >=1.33.1,<2.0.0
• Newer versions of opentelemetry require protobuf >=5.0, but OpenHands had a constraint of <5.0.0

Changes made:

1. Updated opentelemetry-api from 1.25.0 to ^1.33.1
2. Updated opentelemetry-exporter-otlp-proto-grpc from 1.25.0 to ^1.33.1
3. Updated protobuf constraint from ^4.21.6,<5.0.0 to ^5.0.0,<6.0.0

Testing:
Created a test project that depends on both OpenHands and langfuse, and verified that they can be installed together without conflicts.

Note: The comment on the protobuf constraint mentioned that "chromadb currently fails on 5.0+", but chromadb is not used in the codebase, so this constraint was safely updated.

I successfully updated the PR description for PR #8930 to follow the repository's PR template format.

Here's what I did:

1. Examined the PR template from .github/pull_request_template.md to understand the required format
2. Compared it with the current PR description to identify what needed to be changed
3. Created a new PR description that follows the template format while preserving all the valuable information from the original description
4. Updated the PR description directly using the GitHub CLI (gh pr edit)

The updated PR description now includes:

• The required checkboxes at the top (including marking that this change should be included in Release Notes)
• An end-user friendly description section explaining how this resolves a dependency conflict with langfuse
• A detailed summary of what the PR does, including the specific dependency updates and design decisions
• A section for linking to specific issues (marked as N/A since there are no linked issues)

The PR description now properly follows the repository's template format while maintaining all the important technical details from the original description.
