[chore][ping-codeowners-on-new-issue] Ping even if owner filed (open-telemetry#12716)

<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
#### Description
Code owners should be pinged even if a code owner filed an issue. This
helps other code owners, in the case of more than one for a single
component, be notified of relevant issues being filed.

This is the same change as
open-telemetry/opentelemetry-collector-contrib#38841,
as
[requested](open-telemetry/opentelemetry-collector-contrib#38841 (comment)).
