update Babel package

[kvchitrapu]

Upgrade the Babel package to version ^2.12 in response to the Python version upgrade. Fixes #483

@akprasad , python unit tests are failing. You probably noticed it. I don't think this PR broke them.

[akprasad]

looks good, will approve once the tests pass

@akprasad , python unit tests are failing. You probably noticed it. I don't think this PR broke them.

It did, see the logs:

        babel = Babel(app)
>       babel.init_app(app, locale_selector=get_locale)
E       TypeError: Babel.init_app() got an unexpected keyword argument 'locale_selector'

I'll take a look.

@kvchitrapu reverting changes to ambuda/__init__.py fixes the tests locally for me.

@kvchitrapu I updated the PR so tests pass, but docker fails further in:

@akprasad Python 3.10 dependencies have to stabilized. Reverting changes to ambuda/__init__.py fixed unit tests but broke the web app in this manner:

# Extensions
    babel = Babel(app)

    @babel.localeselector
    def get_locale():
        return session.get("locale", config_spec.BABEL_DEFAULT_LOCALE)

Exception:

ambuda-local-ambuda-web-1  | [0]   File "/app/ambuda/__init__.py", line 117, in create_app
ambuda-local-ambuda-web-1  | [0]     @babel.localeselector
ambuda-local-ambuda-web-1  | [0] AttributeError: 'Babel' object has no attribute 'localeselector'

Searching for a solution.

Oh, I think my changes to __init__.py are in error -- please revert them, sorry for the noise. (They are in error because they use the older version of requirements.txt. If we update that file to use the latest version of flask-babel, I think your changes are correct.)

All set. We need to change the Babel instantiation in init.py. The unit tests were working on my laptop, but they were not working in GitHub Actions, as the Ubuntu image is still pulling Flask-Babel v2.x. I forgot to update the requirements.txt file. GitHub Actions should now pull v3.0.1, and the unit tests should succeed.

[kvchitrapu]

@akprasad My bad. I should have dug a little deeper on the unit tests failing in GH actions. All good now. Review and merge when you get a chance.

[akprasad]

Thanks! Looks like the PR history has been mixed with some other work, as I see 27 files changed -- can you clean this up? Once it's pared down I'll merge it in.

Edit: I'll fix this then merge it in.
