Fix number pattern of stringify to support exponential log value

[samchon]

When typia.stringify<T>() be used for an object type which has template typed key containing a number type, and exponential log being used in the template key type, typia could not write the property because regex pattern for numeric value of typia had not supported the exponential log value.

This is an extremely rare case, but fixed for extensionality.

export interface ISomething {
    [key: `value_${number}`]: boolean | string | number;
}

const something: ISomething = {
    "5.175933557310941e-7": -0.170261004873707,
};
typia.stringify(something);
