i18n pipeline

[arbrandes]

Description

For now, this is a discovery: is the frontend-base i18n pipeline fully developed? We might be missing an atlas pull step in our publish pipeline not only for the apps, but for frontend-base itself.  Or maybe this should only happen in frontend-template-site.

Should we ship libraries with full translations?  It seems this would be a new thing: frontend-component-[header|footer] only extract i18n as part of the release workflow, leaving the atlas pull to the MFE.

See this Slack thread for some more context and preliminary findings.
