fix(action): bug report creation was not working (#7371)

## **Description**
The last step of the create-release-pr.yml workflow creates a release
branch, which shall itself trigger another workflow:
create-bug-report.yml. However, there is a security feature in Github
that prevents workflows from triggering other workflows by default. The
workaround is to use a personal access token (BUG_REPORT_TOKEN) instead
of the default GITHUB_TOKEN for the checkout action.
