Mu sets `FLASK_ENV` when running in Flask mode, which is deprecated since Flask 2.2

[pawelad]

What were you trying to do?

Run Mu in Flask mode

What steps did you take to trigger the issue?

Run Mu in Flask mode

What did you expect to happen?

No deprecation warnings displayed

What actually happened?

As I understand it, Mu sets some environment variables when running in Flask mode. One of those variables is FLASK_ENV, which is deprecated since Flask 2.2.0 so a deprecation warning is shown:

'FLASK_ENV' is deprecated and will not be used in Flask 2.3. Use 'FLASK_DEBUG' instead.

What's worse, if I remove that environment variable and add FLASK_DEBUG, the FLASK_ENV is added automatically added by Mu.

I added FLASK_DEBUG, run the app, and checked the current environment variables:

If the team agrees, I'd be happy to help with a PR that switches from using FLASK_ENV to using FLASK_DEBUG.
