Posthog event logging updates

[KIRA009]

What kind of change does this PR introduce?
This PR adds a version number of the openadapt build to posthog events, so its easier to debug the source of erroneous events. It also adds a fix so that submenus in the tray, that have the name of the recording are not reported, rather the underlying action is reported

Summary
Address #768

Checklist

• My code follows the style guidelines of OpenAdapt
• I have performed a self-review of my code
• If applicable, I have added tests to prove my fix is functional/effective
• I have linted my code locally prior to submission

• New and existing unit tests pass locally with my changes

How can your code be run and tested?
In utils.py, comment out the lines that disable posthog in the get_posthog_instance function. I have added a property to psothog events that will differentiate dev events from events coming from the app, so this can be used when we need to test without polluting the events charts. Play around with the tray (also the submenus) and check that the events are logged correctly

@KIRA009 can you please fix merge conflicts? I believe we should pass in recording to get_perf_stats
