Check and update exercise setups names

## Motivation

SecDevLab provides exercises based on OWASP Top 10 since 2021 the vulnerable list has been updated, but some details inside the setup of the exercise don't be updated.

## It would be great if

All exercise setups correspond to correct exercise names.

## What we expect

Check and update all exercise setups to reflect the correct name.


For example, for exercise A1 - Broken Authentication (eCommerce-API) inside `docker-compose.yml` the container name doesn't correspond to the correct numeration, update `a5` to `a1`: [docker-compose.yml#5](https://github.com/globocom/secDevLabs/blob/904a2fb969cb9fb0db30b50709072da8f9d57002/owasp-top10-2021-apps/a1/ecommerce-api/deployments/docker-compose.yml#L5)
