[ext.bridge] Ephemeral kwarg causing errors in defer() and respond()

[krishnans2006]

Summary

Using the ephemeral= keyword argument causes errors when it is passed into the prefix-command version of the bridge command.

Reproduction Steps

Using any ephemeral keyword arguments

Minimal Reproducible Code

    @bridge_command(name="commands", description="This page lists all commands")
    async def _commands(self, context: ApplicationContext) -> None:
        await context.defer(ephemeral=True)
        await context.respond("Commands List", ephemeral=True)

Expected Results

The ephemeral keyword argument should instead be ignored. This could be as simple as a:

if kwargs.get("ephemeral") is not None:
    del kwargs["ephemeral"]

This is in fact exactly what I added in both discord/message.py line 1625 and discord/ext/bridge/context.py line 153 to get it to work temporarily.

Actual Results

Ignoring exception in command commands:

Additional Context

This can also apply to other slash-command-specific kwargs, which I can't specifically think of off the top of my head.
