Make sure to free default `@text` format on error

It seems that bison doesn't call destructors for mid-rule action
components on error, since it does not know their type.

A mid-rule action was used to allocate the "text" string used as format
by string literals without a format, which would leak on error.
This patch replaces it with a new NoFormat component of type <literal>.
Now bison will call jv_free() on that string after a syntax error.

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=60836
