I don't want to downgrade to 2.65, as it does not support newer puppeteer runtimes.

e.g. with 2.65 i cannot use: synthetics.Runtime.SYNTHETICS_NODEJS_PUPPETEER_4_0

There's no reason to bump up the dependencies unless we need something from a newer version. The alpha modules' versioning is awkward such that semver ranges don't quite work the way you expect.

If you want to use a newer version that you have a concrete dependency on, use overrides in your package.json file:

"dependencies": {
  "@aws-cdk/aws-synthetics-alpha": "2.88.0-alpha.0",
  "cdk-monitoring-constructs": "5.3.5",
  ...
},
"overrides": {
  "cdk-monitoring-constructs": {
    "@aws-cdk/aws-synthetics-alpha": "$@aws-cdk/aws-synthetics-alpha"
  }
}
