fix: gracefully handle sentry-sdk < 2.0 in telemetry

[sentry]

This PR addresses an ImportError occurring when codecov-cli attempts to import get_current_scope from sentry_sdk.scope, which is only available in sentry-sdk versions 2.0 and above. The issue arises when the CLI is run in an environment with sentry-sdk v1.x installed, despite pyproject.toml specifying sentry-sdk==2.*.

To fix this:

1. The call to sentry_sdk.get_current_scope().transaction in upload_sender.py is now wrapped in a try/except AttributeError block. This prevents a hard crash if get_current_scope is missing, allowing the CLI to continue execution without Sentry transaction data in such cases.
2. A version check has been added to opentelemetry.py during Sentry SDK initialization. If sentry-sdk version is detected to be less than 2.0, a warning is logged, providing early diagnostic information about the environment mismatch.

Fixes CLI-FW
