`contains` keyword not correctly parsed in composite statements about typedb HOT 2 OPEN

Currently the expected syntax is this:

match
$n contains "hello" isa name;
get;

Which follows the structure of <variable> [<predicate>] [isa <type>];, e.g. $n "Jimbob" isa name; or $a >= 18 isa age;

from typedb.

I don't think this is consistent or intutitive. Currently, all of our constraint forming predicates can be chained into composite statements in the style <type>|<variable> <predicate> <type>|<variable> [, <predicate> <type>|<variable> ...]. This one is the exception to the rule.
