Strapi (#12320)

* Add strapi (ct)

* Update strapi.sh

* Update date_created in strapi.json

* fix(strapi): use official upgrade tool instead of npm install

Replace 'npm install' with 'npx @strapi/upgrade minor --yes' which properly updates dependencies in package.json and runs codemods. See https://docs.strapi.io/cms/upgrade-tool
