Add top issues labeling action

Is your feature request related to a problem? Please describe.
Although I know it is possible to filter top issues using GitHub's reaction filter, I think displaying them in a simple dashboard would give us a better overview of the GRS community's most upvotes features and bugs.

Describe the solution you'd like

I created the top-issues-action following GitHub action to label and display top issues/features/bugs and pull requests. @anuraghazra, maybe adding this cation to the repository is an idea?

@anuraghazra I added an example output in #1935.

@anuraghazra I added this in 663fbae and set it to update every week. It gives me an accessible overview of issues I can work on. Feel free to remove it if you don't like it.
