fix: make telemetry initialization non-fatal

[sentry]

This PR addresses the AttributeError: module 'sentry_sdk' has no attribute 'get_current_hub' issue by making the telemetry initialization process non-fatal.

Root Cause: The original issue stemmed from older CLI versions (specifically cli@10.0.1) where the opentelemetry.py module included an OpenTelemetry integration that internally called sentry_sdk.get_current_hub(). This function was part of the Sentry SDK 1.x Hub API and was removed in Sentry SDK 2.x, which cli@10.0.1 was configured to use. This mismatch caused the AttributeError and crashed the CLI.

Previous Fix: The OpenTelemetry integration, including the problematic SentrySpanProcessor and SentryPropagator imports, was removed from codecov_cli/opentelemetry.py in commit dca7a65 on Jan 21, 2025. This means that CLI versions released after this date no longer contain the code that directly causes this AttributeError.

Current Change: While the underlying bug is resolved in newer CLI versions, this PR adds a defensive try-except block around the init_telem(ctx.obj) call in codecov_cli/main.py. This ensures that if any future Sentry SDK incompatibility or other issue arises during telemetry initialization, it will be caught, logged at a debug level, and will not prevent the CLI from executing its core functionality.

Impact: This change improves the robustness of the CLI. Users running older, affected versions (like cli@10.0.1) are strongly encouraged to upgrade to the latest CLI version to benefit from both the original fix and this added layer of stability.
