chore (update dependencies): manually upgrade the dependency on aws-c…

…dk (#1049)

Dependabot failed to update this dependency, so doing it manually: `yarn upgrade aws-cdk`

Dependabot error:
>  Dependabot cannot update pac-resolver to a non-vulnerable version
> The latest possible version that can be installed is 4.2.0 because of the following conflicting dependency:
> `[email protected] requires pac-resolver@^4.1.0 via a transitive dependency on [email protected]`
> The earliest fixed version is 5.0.0.
