Broken links in tfcall/tfunction help

Help on function tfcall in module valkey.commands.core:

tfcall(
    self,
    lib_name: str,
    func_name: str,
    keys: Union[bytes, str, memoryview, Iterable[Union[bytes, str, memoryview]]] = None,
    *args: List
) -> Union[Awaitable[Any], Any]
    Invoke a function.

    ``lib_name`` - the library name contains the function.
    ``func_name`` - the function name to run.
    ``keys`` - the keys that will be touched by the function.
    ``args`` - Additional argument to pass to the function.

    For more information see https://valkey.io/commands/tfcall/

But https://valkey.io/commands/tfcall/ is a http/404 page

Same goes for the following ones:

• tfcall_async
• tfunction_delete
• tfunction_list
• tfunction_load

I did a bit of digging and it looks like TFCALL and TFUNCTION are part of a Redis Stack feature for triggers that never made it to GA [1][2]. Judging by Valkey's git history, they were never part of the repo. They were introduced in redis-py in mid 2023 [3].
I think it should be safe to delete these commands from valkey-py.
