Fixing azure login for azure container app steps

[twerthi]

---

Background

Customer contacted us to let us know that the Azure Container Apps templates choose the wrong subscription when the provided principal has more than one subscription, it chooses the first one.

Results

This PR fixes adds the -Subscription argument to the login procedure to make sure it logs into the correct subscription when proceeding.

Before

When the tenant has more than one subscription, it shows a warning that it is selecting the first one.

After

Logs into the specified subscription.

Pre-requisites

• Id should be a GUID that is not 00000000-0000-0000-0000-000000000000
  • NOTE If you are modifying an existing step template, please make sure that you do not modify the Id property (updating the Id will break the Library sync functionality in Octopus).
• Version should be incremented, otherwise the integration with Octopus won't update the step template correctly
• Parameter names should not start with $
• Step template parameter names (the ones declared in the JSON, not the script body) should be prefixed with a namespace so that they are less likely to clash with other user-defined variables in Octopus (see this issue). For example, use an abbreviated name of the step template or the category of the step template).
• LastModifiedBy field must be present, and (optionally) updated with the correct author
• The best practices documented here have been applied
• If a new Category has been created:
  • An image with the name {categoryname}.png must be present under the step-templates/logos folder
  • The switch in the humanize function in gulpfile.babel.js must have a case statement corresponding to it
