Add infradev issues to weekly email for PMs to triage and missed SLO

@joshlambert commented on a discussion: In spot checking the infradev board, most issues don't have bug or availability attached: https://gitlab.com/groups/gitlab-org/-/boards/1193197?label_name[]=infradev

To keep things easy, I would propose we include infradev in weekly triage emails and also included in the missed-slo bot: https://gitlab.com/gitlab-org/quality/triage-ops/-/blob/master/policies/stages/hygiene/label-missed-slo.yml This way we don't require additional effort on the Infra team to put a whole bunch of labels on issues when dealing with incidents. I think it's also worth breaking out infradev specifically in the weekly triage report, as the bug section can be large for some groups. Does this seem reasonable? I'm happy to try to craft an MR somewhere in: https://gitlab.com/gitlab-org/quality/triage-ops/-/blob/master/policies/stages/hygiene/label-missed-slo.yml
