(aws-cognito): add ability to use V2_0 as PreTokenGenerationConfig

[kornicameister]

Describe the feature

I want to use Cognito's advanced security for augmenting access tokens per https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-lambda-pre-token-generation.html#user-pool-lambda-pre-token-generation-accesstoken

From what I can tell this should be as simple as setting LambdaVersion to V2_0 of https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cognito-userpool-pretokengenerationconfig.html#cfn-cognito-userpool-pretokengenerationconfig-lambdaversion

Use Case

Changing access tokens

Proposed Solution

add PRE_TOKEN_GENERATION_CONFIG_V2 to UserPoolOperation enum

Other Information

No response

I believe this is already in
userPool.addTrigger( UserPoolOperation.PRE_TOKEN_GENERATION_CONFIG, fnPreTokenGeneration, LambdaVersion.V2_0, )
This results in a V2 trigger and allows to update accesstoken.

LambdaVersion is in aws-cdk-lib/aws-cognito

Thank you @mhboon !

Hi @kornicameister can you validate if this works for you?

@mhboon @pahud my bad, I misunderstood the LambdaVersion as something from lambda alias.
