Don't block the build for translation errors

[Mr0grog]

This allows the translations lint/test step to fail without failing the whole job and thus blocking the build. It logs some summary info for the workflow so it's possible to keep an eye on the status of translation issues.

client/src/intl/en.json, which contains all the translatable text
from the application (probably because you made changes to
the text of a component without updating this file).
