fix: remove mjs support from eslint-config, because it breaks the package.json type module with eslint

removed mjs files in the eslint-config package to fix support issues. Also, adjusted eslint-config postinstall script and tsup.config to reflect the changes made. These changes were to run eslint config with the package.json type module
