Adds a Packages tab to Github repository navigation bar.
This Greasemonkey script adds a "Packages" tab to the repository navigation bar on Github. When viewing a repository, the script adds a new tab that links to the repository's packages page. The link to the packages page is constructed dynamically based on the organization and repository names extracted from the URL.
To use this script, you'll need to have a userscript manager installed in your browser, such as Greasemonkey or Tampermonkey. Once you have the userscript manager installed, you can simply copy and paste the script into a new userscript and save it. The next time you visit a Github repository page, the "Packages" tab should appear in the repository navigation bar.
