Parentheses are not part of the array-literal syntax.  You'd need
something more like
    '{"(\"name\", \"descr\", ...)"}'
and the backslashes would have to be doubled if this is an old-style
string literal.

Personally I'd avoid the thicket of quoting rules and build up the value
using SQL constructs:
    array[row('name', 'descr', ...)::requirement_vo, row(...), ...]
I think casting the first row() to the desired rowtype is probably
sufficient, though it might depend on which PG version you're using.
