Changing weight values should trigger system notes
When changing the weight of an existing issue, a note should be created like the labels, assignees, etc.
- Bolden the weight value and add a comma, making it easier for users to parse the system note, highlighting the changed value.
- This also puts it on par with other system notes that are easy to parse because they have anchoring elements like blue links or labels, which help the value stand out. Boldening is currently applied on title system notes.
