Feature summary (what you would like to be able to do and where):
I would like the "User contributions" link to be moved from the sidebar to a link somewhere in the header of a user page.
Below is a possible placement:

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
While patrolling bad edits on Wikidata I often look at the user page of an editor to see if they have one and it has content and if it doesn't, I then check their talk page to see if anyone has warned them about their edits. I then proceed to check their user contributions to see if the edits I saw were the only bad ones they made or if they made others.
I usually keep my sidebar minimized because it allows me to see the full Wikidata view and I also rarely use the links in the sidebar too.
I would like the "User contributions" link on the sidebar to be moved from the sidebar to the user page header because it is about the only link I do commonly use. It is annoying that it requires me to open the sidebar as well as find it among all of the other small and similar-looking links which slows down my workflow.

Benefits (why should this be implemented?):
Moving it to the user page header would improve the user patrolling and communication workflow that many editors on every Wikimedia site do every day when they navigate between the User page, User talk, and User contributions pages. These are the three core pages of this workflow and it is a hindrance to users that only 2 out of the three are easily and equally accessible through the header.
