Passing built-in functions as function's parameters doesn't work

TCK Test 0092-feel-lambda - 014

Consider this Decision node

<decision name="decision_014_1" id="_decision_014_1">
        <variable name="decision_014_1"/>
        <knowledgeRequirement>
            <requiredKnowledge href="#_bkm_014_1"/>
        </knowledgeRequirement>
        <!-- passed built-in functions as params  -->
        <literalExpression>
            <text>bkm_014_1(abs, sqrt)</text>
        </literalExpression>
    </decision>

It results in the following error:

14:13:47.511 [main] WARN org.kie.dmn.core.util.MsgUtil.logMessage:84 - Parameter 'fn1' is of type 'DMNType{ http://www.montera.com.au/spec/DMN/0092-feel-lambda : lambda_number_returns_number }' but the actual value 'org.kie.dmn.feel.runtime.functions.AbsFunction@7153995c' is not an instance of that type; setting as null

Hi team, thank you for this issue, just FYI, I opened ticket for the editor, as there we miss the support for similar models #1756
