wrong markdownlint docs link

[bbodenmiller]

https://megalinter.io/latest/all_linters/ links to https://github.com/DavidAnson/markdownlint but version 0.45.0 does not existing in that repo, it's actually from https://github.com/igorshubovych/markdownlint-cli

The place to fix it is in the descriptor file, a yaml file with the metadata and install instructions. Check if in the main branch it is fixed, and matches the comment used by renovate to update the versions
