Feature request: Add Cognito trigger schemas

[jkahn117]

Use case

To continue implementation of parser, add schemas for Cognito Lambda triggers. Lambda triggers customize the flow of user pool sign-up, authentication, etc. Details are in docs.

Solution/User Experience

Cognito schemas would be similar to existing schemas in the parser middleware. Many of the schemas would be similar / same.

For example, a basic event schema for the pre-signup trigger:

z.object({
  version: z.string(),
  region: z.string(),
  userPoolId: z.string(),
  userName: z.string(),
  callerContext: z.object({
    awsSdkVersion: z.string(),
    clientId: z.string()
  }),
  triggerSource: z.string(),
  request: z.object({
    userAttributes: z.record(z.string(), z.string()),
    validationData: z.record(z.string(), z.string()).nullable().optional(),
    userNotFound: z.boolean().optional()
  }),
  response: z.object({
    autoConfirmUser: z.boolean().optional(),
    autoVerifyEmail: z.boolean().optional(),
    autoVerifyPhone: z.boolean().optional()
  }).optional()
});
