Update Lambda runtime (#782)

### Feature or Bugfix
Update

### Detail


### Relates
See #655: 
> In Nov 27, 2023 the Lambda runtime node14 and Python3.7 will be
deprecated!

Checked all lambdas that explicitly set the runtime engine: only cognito
httpheader redirection lambda used node14.
All lambdas use python3.8 and node16 or node18.

For cdk dependencies: upgraded to a newest `aws-cdk-lib` `v2.99.0` just
in case if python3.7 is hardcoded somewhere inside of 2.78.0 (shouldn't
be)

### 
Testing: 
- [x] uploaded the changes to my isengard account
- [x] deployment is green 
- [x] could access app page, userguide page, and userguide from the app
page.

### Security
`N/A` - upgraded to a newer version of node js
