docs: update Jira notification channel documentation

[revmag]

Summary

• Document the new Won't-fix resolution field in the Jira alert channel Advanced Options: entering a Jira resolution name (e.g. Won't Do) makes a re-firing alert open a new issue instead of reopening one closed with that resolution.
• Note that the match is case-sensitive and must be the exact resolution name from the project's resolution scheme.
• Clarify precedence: Won't-fix resolution bypasses the Reopen window check entirely.
• Note the bug fix where editing a channel via the UI now preserves an API-set wont_fix_resolution value.
• Add wont_fix_resolution to the API request-body reference table.
• Updated the frontmatter date on the edited file.

Prose-only: PR #12765 merged same-day and the demo lags, so no new screenshots were captured. Feature has no environment gate, so it applies to both Cloud and Self-Host.
