#10243 feat: Add plugin docs to installation errors Pull request opened by AbrhamYishak Description I added the plugin docs to be displayed in the error message when plugin installation fails. I did this by getting the plugin docs from plugin.definition.find_variant() method that returns the variant of a given plugin, then I used the docs of the variant, and if the doc is present, it is added to the error message.
