Adding new properties to session publicData causes type error in blitz-server.ts

### What is the problem?

Adding new properties seems to be causing type error or changing the type of userId to string (uuid)

### Paste all your error logs here:

```ts
Argument of type 'PrismaClient & EnhancedPrismaClientAddedMethods' is not assignable to parameter of type 'PrismaClientWithSession'.
The types of 'session.update' are incompatible between these types.
Type '(args: SelectSubset) => CheckSelect, Prisma__SessionClient<...>>' is not assignable to type '(args: { data: Partial; where: { handle?: string | undefined; }; }) => Promise'.
Types of parameters 'args' and 'args' are incompatible.
Type '{ data: Partial; where: { handle?: string | undefined; }; }' is not assignable to type '{ select?: SessionSelect | null | undefined; include?: SessionInclude | null | undefined; data: (Without & SessionUncheckedUpdateInput) | (Without<...> & SessionUpdateInput); where: SessionWhereUniqueInput; }'.
Types of property 'data' are incompatible.
Type 'Partial' is not assignable to type '(Without & SessionUncheckedUpdateInput) | (Without<...> & SessionUpdateInput)'.
Type 'Partial' is not assignable to type 'Without & SessionUpdateInput'.
Type 'Partial' is not assignable to type 'Without'.
Types of property 'userId' are incompatible.
Type 'string | null | undefined' is not assignable to type 'undefined'.
Type 'null' is not assignable to type 'undefined'.
```

### Paste all relevant code snippets here:

```ts
import {SimpleRolesIsAuthorized} from '@blitzjs/auth'
import {GlobalRole, MembershipRole} from 'db'

export type Role = MembershipRole | GlobalRole

declare module "@blitzjs/auth" {
export interface Session {
isAuthorized: SimpleRolesIsAuthorized
PublicData: {
userId: string
isAdmin: boolean
role?: GlobalRole
orgRole?: MembershipRole
orgId?: string
}
}
}

```

### What are detailed steps to reproduce this?

1. i believe this happens when adding properties to the session data.
2. i could reproduce this twice but reverting it to original doesnt seem to fix it so i am not certain.
