Mixin: Rename exclusion rule from `panel-job-instance-rule` to `target-instance-rule`
Mixin: Rename exclusion rule from `panel-job-instance-rule` to `target-instance-rule`

Within https://github.com/grafana/dashboard-linter/commit/9a32e58ed01ee136ea674887f04a559a15eda3e6, the rules have been split into two different rules:

`target-job-rule`
`target-instance-rule`

All of our queries do contain the `job` label but as per the reason, we don't need both in this particular case.

Fixes #2899
