/**
* Create a middleware that validates `wallet_requestPermissions` calls that
* include the `wallet_snap` permission.
*
* This prevents requesting the `wallet_snap` permission in the same call as
* other permissions, which could lead to a confusing user experience where
* multiple permission screens are shown at once, or the other permissions are
* not displayed properly because the `wallet_snap` permission screen takes
* precedence.
*
* @returns The middleware.
