update tar command in the readme

[Scorp10N]

first, thank you for this helpful repository! :) i'm learning a lot from it.

last commit #60 changed directory structure without updating readme file
in tar commands paths need to reflect the updated folder structure "microservices-xxx"

for example:
'tar -zcvf env-template.tar.gz environment/' => 'tar -zcvf env-template.tar.gz microservices-env/'

ps. i wonder if 'readme.md' can be generated or referenced through dynamic relative paths

Same here - glad someone noted this - I was looking for the directory and then it became obvious with the example above (this is for the loadbalanced ecs sample) - https://github.com/aws-samples/aws-proton-cloudformation-sample-templates/tree/main/loadbalanced-fargate-svc
