Set up Structured Issue Metadata

[jamietanna]

Per https://github.blog/changelog/2026-03-12-issue-fields-structured-issue-metadata-is-in-public-preview/

• External issue reference
  • For Mend-specific JIRA issues
  • May also be useful for maintainers who are tracking through their own issue tracker
  • Note: this is only visible to collaborators on the project (Triage+)
• Start using the default field for Priority
• Manager/Datasource/etc
  • Related: ci: script the syncing of Datasource/Manager/Platform to a GitHub label #41814
• Update docs/development/issue-labeling.md

This will require:

• A one-time pass to migrate labels -> fields, for:
  • Priority
  • Manager/Datasource/etc
• Updating tools/docs/github-query-items.ts etc
• Updating Issue template
  • https://github.com/orgs/community/discussions/189141#discussioncomment-16276936
• Updating Issues with missing labels #33236

Aside: I've requested access in https://github.com/orgs/community/discussions/189141

@secustor suggested that there may be some specific fields for bugs - what were you thinking?

My initial thought has been something like sub types for regression e.g. introduced in version X. Though this maybe overkill in the end.

Might not be able to use this for Managers: #42131 (comment)
