Add a self-deployment guide for the new `wechatcom_kf` channel under
`docs/channels/wecom-kf.mdx` in zh / en / ja, mirroring the existing

`docs/docs.json`.

Secret (push-to-phone) / Token / EncodingAESKey, configuring `config.json`,
saving the callback URL + Enterprise Trusted IPs, binding the WeCom
Customer Service account, and distributing the access link / QR code.
