Adding to Sedat SALMAN suggestions - Just to confirm, are you leveraging Azure App Service or App Service Environment?   
For your reference, you may checkout this GitHub repo (personal) from one of my colleague: Using wkhtmltopdf (dinktopdf) with Docker and Azure App Service  -This repo demonstrates how to use DinkToPdf which is a Nuget package that acts as a wrapper around the very popular wkhtmltopdf library to provide HTML to PDF generation capabilities.
Refer App Service Sandbox GitHub wiki (official): pdf-generation-from-html (sandbox restrictions) and Unsupported frameworks  
As a side note -Windows Containers on Azure App Service -many PDF generation libraries make calls to graphics device interface (GDI) APIs, within a Windows container these calls will succeed.
						
It looks like you're trying to install wkhtmltopdf on the GitHub Actions runner, but this does not make it available in the Azure App Service environment. To resolve this issue, you need to ensure that the wkhtmltopdf executable is available within the Azure App Service environment where your application runs.
