Support Protobuf 5+

[Alive-Fish]

What happened?

When I tried to use autogen-ext in our project, there are conflicts between it and original packages. It told that the autogen-ext depended on a old version of protobuf. Is there some way to upgrade it

(.venv) D:\vscps\teams-copilot-ext>poetry add autogen-ext
Using version ^0.4.2 for autogen-ext

Updating dependencies
Resolving dependencies... (6.0s)

    Because no versions of autogen-ext match >0.4.2,<0.5.0
 and autogen-ext (0.4.2) depends on autogen-core (0.4.2), autogen-ext (>=0.4.2,<0.5.0) requires autogen-core (0.4.2).
(1) So, because autogen-core (0.4.2) depends on protobuf (>=4.25.1,<4.26.0), autogen-ext (>=0.4.2,<0.5.0) requires protobuf (>=4.25.1,<4.26.0).

    Because no versions of opentelemetry-exporter-otlp-proto-grpc match >1.28.2,<1.29.0 || >1.29.0,<2.0.0
 and opentelemetry-exporter-otlp-proto-grpc (1.29.0) depends on opentelemetry-proto (1.29.0), opentelemetry-exporter-otlp-proto-grpc (>1.28.2,<2.0.0) requires opentelemetry-proto (1.29.0).
    And because opentelemetry-proto (1.29.0) depends on protobuf (>=5.0,<6.0), opentelemetry-exporter-otlp-proto-grpc (>1.28.2,<2.0.0) requires protobuf (>=5.0,<6.0).
    And because opentelemetry-exporter-otlp-proto-grpc (1.28.2) depends on opentelemetry-proto (1.28.2)
 and opentelemetry-proto (1.28.2) depends on protobuf (>=5.0,<6.0), opentelemetry-exporter-otlp-proto-grpc (>=1.28.2,<2.0.0) requires protobuf (>=5.0,<6.0).
    And because autogen-ext (>=0.4.2,<0.5.0) requires protobuf (>=4.25.1,<4.26.0) (1), autogen-ext (>=0.4.2,<0.5.0) is incompatible with opentelemetry-exporter-otlp-proto-grpc (>=1.28.2,<2.0.0)
    So, because teams-copilot-extension depends on both opentelemetry-exporter-otlp-proto-grpc (^1.28.2) and autogen-ext (^0.4.2), version solving failed.  

What did you expect to happen?

No issues when adding autogen-ext.

How can we reproduce it (as minimally and precisely as possible)?

Install the following packages by poetry.

opentelemetry-exporter-otlp-proto-grpc = "^1.28.2"
autogen-ext = "^0.4.2"

AutoGen version

0.4.2

Which package was this bug in

Core

Model used

gpt-4o

Python version

3.12.8

Operating system

Windows 11

Any additional info you think would be helpful for fixing this bug

The reason for the current protobuf version selection was due to constraints imparted by open telemetry.

It looks like support has now been merged and is now released. So we should be able to move to protobuf 5+

Great! Thank you!
