Fix confusion with the use of the Add Issue button on boards
Problem to solve
The placement and color of the Add issue button on boards and its similarity to New Issue from almost all other issue-based pages is confusing. At least once a week I click Add issue when I'm in the board view meaning to create a new issue for this project.

Proposal
Perhaps the gitlab-ce~2024184 team will have a better idea, but I proposal either (or some combination):
- Rename, re-color or move the
Add Issuebutton to prevent confusion - Given the added features of board filters, columns for assignee and milestone - is the
Add Issuebutton still useful for people? Would it make more sense to replace theAdd Issuebutton with theNew Issuebutton found on the list view and issue view?
What does success look like, and how can we measure that?
Users are less confused about the difference in buttons given the area of issues they are in.
