    Downloads an image from the specified URL, converts it to grayscale, and generates a histogram of its grayscale values.

    Parameters:
    - url (str): The URL of the image to be downloaded. Must be a valid URL pointing to an image.

    Returns:
    - matplotlib.axes._axes.Axes: The Axes object of the generated histogram.

    Raises:
    - ValueError: If the URL is invalid or if there's an error downloading the image. Error message will specify the download issue.
    - IOError: If there's an error in opening or processing the downloaded image. Error message will specify the processing issue.

    Requirements:
    - requests
    - PIL
    - numpy
    - matplotlib.pyplot

    Example:
    >>> ax = task_func("https://www.example.com/myimage.jpg")
    >>> type(ax)
    <class 'matplotlib.axes._axes.Axes'>

instruct prompt

Downloads an image from the specified URL, converts it to grayscale, and generates a histogram of its grayscale values.
The function should raise the exception for: ValueError: If the URL is invalid or if there's an error downloading the image. Error message will specify the download issue. IOError: If there's an error in opening or processing the downloaded image. Error message will specify the processing issue.
The function should output with:
    matplotlib.axes._axes.Axes: The Axes object of the generated histogram.
You should write self-contained code starting with:

Code

import requests
from PIL import Image
import numpy as np
import matplotlib.pyplot as plt
def task_func(url: str) -> "matplotlib.axes._axes.Axes":
