Combine iOS and macOS triage links since it's completed in the same meeting.
1. Remove `no:assignee` from both incoming issue links, as these should still be triaged.
2. Combine P0 issue and packages PR links. Other links are harder to combine. For example, macOS PRs looks for `"affects: desktop"` but iOS PRs do not.
*Replace this paragraph with a description of what this PR is changing or adding, and why. Consider including before/after screenshots.*
*List which issues are fixed by this PR. You must list at least one issue. An issue is not required if the PR fixes something trivial like a typo.*
*If you had to change anything in the [flutter/tests] repo, include a link to the migration guide as per the [breaking change policy].*
Noticed the framework triage was doing this, adopting it for design languages as well!
Critical triage follows up on these draft PRs if they sit for long without an update. Having draft PRs allows folks to discuss changes without getting nudged constantly to make progress on it. This feels like a really positive change.
Currently the ecosystem team triages all PRs in the packages repository, but the platform teams also triage all PRs with their platform label. Due to the way PRs in packages work, however, it's relatively common for a PR to not be relevant to all the teams' triages at all times. Common examples:
- One platform team may LGTM a multi-platform PR for their platform's portion, while another platform goes through review for several more weeks.
- A cross-platform PR may not have high-level design approval from the ecosystem owner, at which point platform implementation review is premature.
To avoid PRs showing up repeatedly in a platform team's triage when it's not relevant, this adjusts the triage structure:
- Queries for PRs in platform teams query `triage-<platform name>` rather than `platform-<platform name>`
- Ecosystem triage will add the `triage-<platform name>` label during triage when a PR is ready for that platform team's consideration.
- Platform teams can remove the label when it's not relevant to them (e..g, after it's been LGTM'd for that platform).
This also adds a desktop PR query, since there wasn't one, covering the separate platforms. They are separated to allow for more triage flexibility in the future.
