Dependabot PR trigger a false positive

[Th3S4mur41]

GitHub's accessibility alt text bot is complaining about images missing alt text in dependabot PR

Uh oh! https://github.com/dependabot[bot], the image you shared is missing helpful alt text. Check your pull request body.

Alt text is an invisible description that helps screen readers describe images to blind or low-vision users. If you are using markdown to display images, add your alt text inside the brackets of the markdown image.

Learn more about alt text at Basic writing and formatting syntax: images on GitHub Docs.

The only image in the PR is the compatibility score which does have an alt text

[![Dependabot compatibility score](https://dependabot-badges.githubapp.com/badges/compatibility_score?dependency-name=github/accessibility-alt-text-bot&package-manager=github_actions&previous-version=1.2.0&new-version=1.3.0)](https://docs.github.com/en/github/managing-security-vulnerabilities/about-dependabot-security-updates#about-compatibility-scores)

Here the HTML output as well to verify:
