discord.PermissionOverwite cannot set kwargs or any other attrubute

[shadeyg56]

Summary

I am attempting to use discord.PermissionOverwrite to overwrite permissions for a channel. Upon setting the read_messages or send_messages kwargs or attributes it returns an error AttributeError: PermissionOverwrite' object attribute 'read_messages' is read-only`

Reproduction Steps

1. create a basic command
2. assign discord.PermissionOverwrite() to a var
3. attemp to set read_messages to True
4. run command and see traceback

Minimal Reproducible Code

@commands.command()
async def test(self, ctx):
    overwrite = discord.PermissionOverwrite()
    overwrite.read_messages = True # this line causes error
    overwrite.set_messages = True # this line also raises error. I have not tried with any other perms
    # discord.PermissionOverwrite(read_messages=True) raises same error

Expected Results

No error should be returned and should be able to set kwargs in constructor or attributes

Actual Results

AttributeError: 'PermissionOverwrite' object attribute 'read_messages' is read-only is raised
