[heft] upgrade or add jest 28/29 plugins

[jessekrubin]

I usually don't question the pace of the rush repo but at the same time I am irked (might be irrational) by my heft-jest-plugin projects using jest 27.

Now that jest is on v29 I think we (I consider myself a rusher now (even if ya don't)) should aim to not be behind more than one major release.

PS: on a semi related note I should really find the time to PR in my tap and vitest heft plugins which (for me and my team) seem to work p well (just gotta clean them up (a bunch)). My team is often using a hybrid version of the heft jest plugin and my messy vitest plugin.

PPS/PSS: I really dislike jest but heft + jest is 🔥 so hats off to everyone involved.

Sounds like a good idea. We'll need to look through the breaking changes both to the runtime and the APIs, but hopefully that won't be too complicated.

Are there any updates or available timelines regarding updated Jest support? We're running into more and more ESM-only modules which is causing lots of additional workaround work for us to keep tests running as our app evolves.
