docs: add info about PPE pricing model to Academy

[TC-MO]

Added new section about PPE pricing model
Added screenshot reflecting UI in the Console for PPE pricing model Added tip about naming of events in the PPE Actors Added TODOs

Before the monetization is available to all creators, i.e. all creators can set it up themselves, I wouldn't add it to docs, or at least I'd frame it in a way that if they want to have this feature enabled, they need to contact us. What do u think?

[TC-MO]

Is there any concrete ETA for releasing it to all creators? I'm asking because I can see few solutions

1. If it is close ETA then add note about availability as you suggested and release docs with such note, to be removed once PPE is generally available
2. If it not a close ETA then remove mentions of PPE untli it is GA

[TC-MO]

After further thinking I would propose to:

• Shelve this PR untli PPE is GA and then fill in the blanks regarding the payout & best practices
• Move forward with the docs: restructure content and enhance model descriptions #1279 since the goal there is to just have all possible pricing models that user might encounter in one place (and we have working PPE Actors in Store)

Thoughts?

No exact ETA, but I think general availability is a couple of months away at this point.

Agree with your suggestion
