Update `FunctionBodyGenerator` for `NodeFactory.createOnFailClauseNode` change

[MaryamZi]

Description: With https://github.com/ballerina-platform/ballerina-lang/pull/41049, we are adding support for error typed binding patterns in the on-fail clause.

With this, NodeFactory.createOnFailClauseNode changes from

    public static OnFailClauseNode createOnFailClauseNode(
            Token onKeyword,
            Token failKeyword,
            TypeDescriptorNode typeDescriptor,
            IdentifierToken failErrorName,
            BlockStatementNode blockStatement) {

to

    public static OnFailClauseNode createOnFailClauseNode(
            Token onKeyword,
            Token failKeyword,
            TypedBindingPatternNode typedBindingPattern,
            BlockStatementNode blockStatement) {

We need to update usage in https://github.com/ballerina-platform/graphql-tools/blob/main/graphql-code-generator/src/main/java/io/ballerina/graphql/generator/client/generator/ballerina/FunctionBodyGenerator.java#L281 and pass a typed binding pattern (similar to https://github.com/ballerina-platform/graphql-tools/blob/main/graphql-code-generator/src/main/java/io/ballerina/graphql/generator/client/generator/ballerina/FunctionBodyGenerator.java#L401) instead of the type descriptor and identifier separately.

Timestamped version with the change - 2201.8.0-20230720-214400-9518f4f5

We are planning on adding this to update 8.

Keeping this on-hold, as the related language side changes are expected to be shipped with U9.
