Specify Python 3.7 Runtime for Azure app

[tdowrick]

Without a runtime version specified, Python 3.10 is installed.

Not all of the package versions pinned in requirements.txt are compatible with 3.10 and the app launch fails.

Using Python 3.7 as this is the same version as specified in the anaconda environment config.

/azp run

@peterhessey , something's wrong with the actions here, they don't start. Maybe push a dummy commit to trigger again? (/azp run did not have any effect because it's a Github action)

[ant0nsc]

... Looking at the workflow again, I'm not sure the trigger conditions are correct. Here's what we have in hi-ml:

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

[ant0nsc]

@tdowrick , could you please merge the latest main into your branch, so that we can merge this PR?
@peterhessey FYI
