Include the issue and pull request sidebar as a method for assigning users

[labrose]

What article on docs.github.com is affected?

https://docs.github.com/en/github/managing-your-work-on-github/assigning-issues-and-pull-requests-to-other-github-users

What part(s) of the article would you like to see updated?

Today the assigning article relies heavily on using the list of issues, but does not mention that users can also assign individual issues to users via the sidebar assignees control.

It would be great to highlight the use case of assigning to an individual, including the quick "assign yourself" action in our documentation.

@labrose Great catch! I think the procedural in this article could be completely updated to match the flow in the gif.

Anyone is welcome to open a pull request to make this change! You'll need to update all of the steps and take new screenshots (without any of your personally identifying information).
