Describe the bug
When the name: within azure.yaml contains a slash / character, it breaks the packaging of services.

error that ocurrs:

root@MacBookPro azd-react-bootstrap-dashboard # azd package api

Packaging services (azd package)

  (x) Failed: Packaging service api

ERROR: failed packaging service 'api': failed when creating zip package to deploy api: open /tmp/build5nines/azd-react-bootstrap-dashboard-api-azddeploy-1734478898.zip: no such file or directory

To Reproduce

1. change the name: of the template in the azure.yaml file to have a slash / character in it; such as `build5nines/azd-react-bootstrap-dashboard'
2. add a service for a web project, such as a node.js app

Expected behavior
It's expected that the service packaging complete successfully, or gives a warning that the name contains an invalid character.

root@MacBookPro azd-react-bootstrap-dashboard # azd package api     

Packaging services (azd package)

  (✓) Done: Packaging service api
  - Package Output: /tmp/build5nines-azd-react-bootstrap-dashboard-api-azddeploy-1734479080.zip

  (-) Skipped: Packaging service dashboard

This issue can be reproduced, and we will fix it in the following approach:

If there is a slash / in the "name:" of azure.yaml, change the / to - when packaging without any prompts.
