[repo] Switch core-version-update workflow to use a dedicated bot account

[CodeBlanch]

Changes

• Use a dedicated bot account for the core-version-update.yml workflow

Details

Relates to open-telemetry/opentelemetry-dotnet#5657

Previously we were using the github-actions bot with workflow permissions. However things done in that context (push, create pr, publish release, etc.) don't trigger other workflows. So the PRs which are opened won't have CI run for example. The recommendation (see: open-telemetry/community#2127 (comment)) was to use OpenTelemetryBot instead which is more or less a normal account.

Demo PR: CodeBlanchOrg#3

Note: That demo shows CodeBlanchBot because it is my test org but when run here it will be OpenTelemetryBot.
