misc doc updates for upcoming v0.5.0

[krancour]

I'm still looking for more items, but I found two things already in the docs that need to be updated and were overlooked until now:

• Freight and FreightReference types have lost their id field since refactor!: remove id field from Freight and FreightReference types #1609, but it still appears in a few places in docs

• Docs mention a verificationResult field, which is actually verificationInfo. I believe the composition of that type might have changed, and we're also recording VerificationHistory now as well since feat(controller): record verification history Stage #1645.

• Freight has a new alias field, which is a convenience over the alias label. refactor: add alias field to freight; add default alias in webhook #1612

• Warehouse scanPaths and ignorePaths are a major new feature being introduced in feat(api/controller): support filtering rules Git subscriptions #1477. That PR doesn't contain documentation, so we will have to add it separately.

I'll update this list if/as I find more items.

@hiddeco if you have the bandwidth, would you be able to look at this?
