Your command is out of the cog and also, you are using client.tree.command, that decorator is only available outside cogs, in the main file. For cogs must use app_commands.command decorator. Also, try to use cog classes outside the main file to prevent errors.

import discord
from discord.ext import commands
from discord import app_commands
from discord import Interaction

# This must be in your main file, not in the cog one
client = commands.Bot(..)

# This must be in another file
class Ping(commands.Cog):
    # __init__ is unnecessary, the class auto applies the client parameter
    @commands.Cog.listener()
    async def on_ready(self):
        ...

    @app_commands.command(description = "Shows bot current latency in ms.")
    async def ping(self, interaction:discord.Interaction):
        bot_latency = round(self.client.latency * 1000) # here you can also use interaction.client.latency instead of self.client.latency
        await interaction.response.send_message(f"Pong! Bot latency is `{bot_latency}`ms")

async def setup(client):
    await client.add_cog(Ping(client))
