Mixin: `template-job-rule` now only validates job and not both instance and job (#2944)
Mixin: `template-job-rule` now only validates job and not both instance and job (#2944)

With https://github.com/grafana/dashboard-linter/pull/49 `template-job-rule` no longer validates both `instance` and `job` labels. Add the new rule of `template-instance-rule` to the exclusions to preserve the previous behaviour.
