ci: force PyPI botocore so awslocal works on GitHub runners - #275

Conversation
The GitHub-hosted runner ships a Debian de-vendored system botocore
(python3-botocore, no botocore.vendored subpackage). pip treats
boto3/botocore as already satisfied and never installs the PyPI build,
so awslocal's unguarded 'from botocore.vendored.requests...' import in
awscli's s3transfer fails with:
ModuleNotFoundError: No module named 'botocore.vendored'
This broke ~20 samples' 'make test-ci' at the awslocal step. Installing
PyPI boto3/botocore into the user site shadows the system package and
restores botocore.vendored.

Creating an AWS::ElasticLoadBalancingV2::LoadBalancer (ALB) requires at
least two subnets in two different Availability Zones. The sample defined
only one subnet, so 'make test-ci' failed at deploy with:
CREATE_FAILED: LoadBalancer ... ValidationError: At least two subnets
in two different Availability Zones must be specified
Widen the VPC to /16 and add a second /24 subnet in AZ index 1, wiring
both into the load balancer. Verified locally against LocalStack Pro:
stack deploys and both ALB endpoints (/hello1, /hello2) return HTTP 200.
