Add `needs-design-feedback` keyword to Trac

[desrosj]

In ​this post on the ​Make WordPress Design blog, a ​decision made during a weekly design meeting was summarized.

The proposed change was to consolidate 3 design related keywords into 2.

• ‘ux-feedback’ and ‘ui-feedback’ will now merge into needs-design-feedback.
• needs-design will remain and indicate that a designer needs to create a specific design.

In 4258.diff​:

• Remove the ui-feedback and ux-feedback in favor of the needs-design-feedback keyword.
• Update the description of the needs-design keyword for added clarity to its purpose.

After this change is deployed, I think that only the following report will need to be updated:

• ​https://core.trac.wordpress.org/tickets/ux-feedback

In 8441:

Trac: Remove ui-feedback and ux-feedback keywords in favor of needs-design-feedback.

Update the description of needs-design keyword for added clarity to its purpose.

Props desrosj.
Fixes #4258.

Re-opening for

• Trac cache-buster so browsers get the new JS That was done in [8442]
• Trac Reports need their 'Workflow' sections updated (All reports with a Workflow section, not just UX/UI/Design reports)
• Trac Reports might need renaming

I've Updated ​https://core.trac.wordpress.org/tickets/ux-feedback to

• Also include the new keyword as a separate group from the existing tagged items (They can be bulk updated to the new keyword if someone wanted to, but
• Changed the title to 'Needs Design Feedback'
• The URL probably requires a systems-level change if we want that updated
• Links to that report probably need updating in various locations.

Thanks for following up on this, @dd32! I was waiting for the cache to bust before updating the reports.

@karmatosed and the design team plan to scrub all of the tickets with the old keywords manually to prevent having to bulk edit them.

I think displaying the tickets in a separate group on that report, for now, is great.

Eventually, we'll want a new report or a new alias for /report/35.

Let me know if I can help at all with the rest of the changes.
