Added support for rendering the `README.md` file with a markdown parser, allowing users to customize the behavior with new flags. The `-r=false` flag can be used to disable rendering of the README.md file if no file is provided.
Updated the `cmd/root.go` file to include the new flags and updated the `pkg/client.go` file to reflect the changes in the client struct.
This commit updates the go-grip project to use golangci-lint for code quality checks, improves the build process by adding a check for formatting errors, and enhances the release workflow by using the new golangci-lint action.
The changes address issues with code quality and maintainability, ensuring that the project adheres to best practices. The improved build process reduces the risk of formatting errors, while the updated release workflow ensures that the project is properly formatted before being released.
