Feature request: Add argument to issue_close() that allows for a comment to be posted to the issue before closing it

[larnsce]

Hi @rundel, I am now on the other side of things. I have a list of issues where participants have fixed errors and files now render. I would like to use the issue_close() function, but still add a comment before close the issue.

My feature request:

Add argument to issue_close() that allows for a comment to be posted to the issue before closing it. Example:

issue_close(repo = repo, number = 1, comment = "Thanks, your homework assignment is completed.")
