[SasinduDilshara]

Purpose

Add read functionality for Ballerina json data types with jsonpath expressions.

import ballerina/data.jsondata as jsondata;

json store = {
    store: {
        book: [
            {
                category: "reference",
                author: "Nigel Rees",
                title: "Sayings of the Century",
                price: 8.95
            },
          ....................
        ],
        bicycle: {
            color: "red",
            price: 19.95
        }
    },
    expensive: 10
};

function test1() returns json|error {
    return check jsondata:read(store, `$.store.book[*].author`);
}

Fixes ballerina-platform/ballerina-library#5938

This commit 5a659c3 contains the base for the jsondata library and it is building properly. It would be better, if you add your changes on top of this. WDYT? @SasinduDilshara @hasithaa

Lets add the commit as a PR, then I will rebase it based on that.

Mark this as a draft since, the PR that contains base files should be send before this

@SasinduDilshara Still windows GrallVM validation fails.

Had a chat with @TharmiganK regarding these failures, This is because this GraalVm checks test with Lang-master branch,

I was able to produce that locally now. Will fix it
