/**
 * Applies a predicate function to a specified property of an object. This
 * function extracts the given property from an object and applies the provided
 * predicate to it, returning the result.
 *
 * @example
 *
 * ```ts
 * let isPositive = (x: number) => x > 0
 * let testValue = applyToProperty('value', isPositive)
 *
 * console.log(testValue({ value: 10 })) // true
 * console.log(testValue({ value: -5 })) // false
 * ```
 *
 * @template T - The type of the object.
 * @template K - The key of the property in the object.
 * @param property - The property name to extract from the object.
 * @param predicate - The predicate function to apply to the property's value.
 * @returns A function that takes an object of type T and applies the predicate
 *   to its specified property.
