Fix value conversion error for inline record creation with special characters

[HindujaB]

Purpose

$subject

Fixes #41633

Approach

As we use the decoded identifiers in the value conversions, the generated record value creators should have the same representation in the switch cases. This PR fixes it by using the Utils.unescapeBallerina() API.

Samples

import ballerina/io;

public type Copybook record {
    DFHCOMMAREA DFHCOMMAREA?;
};

public type DFHCOMMAREA record {
    record {
        string MI\-HDR\-VERSION?;
        string MI\-HDR\-MSGID?;
        string MI\-HDR\-LOGGINGID?;
        record {
            string MI\-HDR\-REPLYQMGR?;
        }[2] MI\-HDR\-REPLYSTACK?;
    } BROKER\-MESSAGE\-AREA?;
};

public function main() returns error? {
    string s = string `{
    "DFHCOMMAREA": {
        "BROKER-MESSAGE-AREA": {
            "MI-HDR-VERSION": "2",
            "MI-HDR-MSGID":"3238763233323598798798712321187612",
            "MI-HDR-LOGGINGID": "Z5118761-Z"
        }
    }
    }`;
    json rec = checkpanic value:fromJsonString(s);
    map<json> mapJson = check rec.ensureType();
    Copybook dfhcommarea = check mapJson.cloneWithType();
    io:println(dfhcommarea.DFHCOMMAREA?.BROKER\-MESSAGE\-AREA);
}
