This is no longer an enum, so we cannot reliably
translate it.

This accepts data from the updated backend
(from the previous commit) but does not display
any of the new metadata yet.

This is not tested with search results, because I could
not obtain search results locally. Suggestions on the
home page work, but no results are shown in /search

repaired UI display of types and languages as it was again hidden behind the exercise cards on small screens

In the escape sequence "·" there was unicode
code point 0332 (UTF-8 cc b2), which is a
"combining low line". I think this does not belong
in there.

The exercise metadata component is only rendered
when it gets a value which is not null and has
a length of at least one (either string or array).
If it gets a value which is translated before it
is being passed, the result will be something of
the form "translation-not-found[...]", which has
a length of at least one, so it is rendered.
To prevent this, check if a value is set before
translating it.

They were replaced with exercise-metadata-item.
