Docs Transaction: Clear documentation on when a query (promise) can be created and used in a Txn

[richard-stafflink]

It is unclear of when a promise (query or mutation) can be created that we want included in a trasaction.
When a promise is created, it is most comment for the I/O call to be made immediately.
I'm hoping this is not the case for Prisma queries/mutation (just like GQL dataloaders).

There was an old issue discussing clarification back in V3, and the result was the Prisma doco being updated: prisma/prisma#13564 (reply in thread)

Since then, and a few versions of the doco later, this info is missing.

So it would be nice to update the doco if this is still the case.

NOTE: in order for the promise to only fire when await/then, and not immediately, there would have to be a process.nextTick() (or a zero setTimeout)` - does that sound right?

Hey @richard-stafflink, it seems like your question has been addressed by the link Jan shared earlier.

If you feel like we still need to update the docs, please feel free to re-open the issue 🙏
