KV Namespace needs to be created

[abdulisik]

Hey @jarylc, I gave this a try and it looks good, thank you!
I might be creating a pull request regarding this issue, and a few other things on my mind. For now, here's the issue.
The kv_namespaces in wrangler.toml needs to be set up.
https://github.com/jarylc/cf-workers-chatgpt-discord-bot/blob/66d1205c25bdeb9c1b8bda5ea60cc66292010d9a/wrangler.toml#LL7C62-L7C62
I ran npx wrangler kv:namespace create CHATGPT_DISCORD_BOT_KV in order to create a new namespace and pasted that ID in my wrangler.toml. This should be a step in 'Getting Started'.

Ah, I should've added a step to remove those lines if you don't want to create a KV and have context.

Made README.md slightly clearer
