fix: ensure endpoint group weight 0 is taken into account

[yannrouillard]

Zero is a valid value for an endpoint group configuration and it shouldn't be ignored and not sent to the API.

The current behaviour causes a endpoint weight of 128 to be used instead as it is AWS default value if no weight is set. This causes traffic to be sent despite the expectations that a zero value will cause no traffic on the endpoint.

Description

This Pull request fix the issue #31254 where a zero value for a global accelerator endpoint group configuration is ignored despite being a valid value.

Closes #31254
