fix: remove invalid bullet format from ReactQuill configs

[SueJianjian]

Summary

Closes #6581

• removes the invalid bullet entry from the Quill formats arrays
• keeps list in place, which already covers ordered and bullet lists
• updates both affected components to avoid the browser console error consistently

Why

Quill expects list in the formats array, while bullet is only used as a toolbar value such as { list: "bullet" }.

Having bullet inside formats causes the console error:

Cannot register bullet specified in formats config

Change

• update keep-ui/features/alerts/alert-note/ui/alert-note-modal.tsx
• update keep-ui/features/incidents/create-or-update-incident/ui/create-or-update-incident-form.tsx

Validation

• verified both affected files contain the invalid bullet entry in formats
• removed only bullet and left the existing toolbar config unchanged
• scope kept intentionally minimal because the issue is a direct config mismatch

Notes

• I did not broaden this into a richer editor refactor or toolbar behavior change.
