After #2718 was merged into the trunk, the trunk CI reported an error, which resulted in the inability to merge subsequent PRs.

The main CI project fails, and the error message is as follows:

What you expected to happen:
The master CI is running normally

How to reproduce it (as minimally and precisely as possible):
make update-development-yaml

Anything else we need to know?:

Environment:

• Volcano Version:

In #2718, the transfer characters of some keywords in legendFormat are cleaned up, such as: le, queue, job_namespace, and volcano-namespace.

According to the description of #2717 to fix the problem, this time the definition in grafana.yaml will be restored to 1773 state

Sorry for the trouble. I removed the '\' around '{{' to make it looks good as a grafana dashboard. But I didn't realize that it'll break the helm template command. The correct way to escape double curly brackets in Go templates is like {{ "{{queue}}" }} or {{ ` {{queue}} ` }}.

It’s okay, we are very happy that you can contribute. I will first restore grafana.yaml to the state with \ to ensure the normal operation of CI. If necessary, you can optimize it according to your needs and run make update-development-yaml Guarantee that the result is passed.
