Composer upgrade

Related to https://github.com/keyclampstore-com/m/issues/17, https://github.com/…keyclampstore-com/m/issues/12 https://github.com/fooman/emailattachments-m2 ```text Root composer.json requires fooman/emailattachments-m2 3.6.1, it is satisfiable by fooman/emailattachments-m2[3.6.1] from composer repo (https://repo.packagist.org) but fooman/emailattachments-m2[1.0.0, 2.0.0, ..., 2.1.0, 3.1.1, ..., 3.4.0] from composer repo (https://repo.magento.com) has higher repository priority. The packages from the higher priority repository do not match your constraint and are therefore not installable. That repository is canonical so the lower priority repo's packages are not installable. See https://getcomposer.org/repoprio for details and assistance. ```
