fix(agoric-cli): handle another vstorage error variation (#9024)

fixes #9033

avoid:

```
Error#1: error code 18 reading data of published.wallet.agoric1l...: failed to load state at height 14007...; version mismatch on immutable IAVL tree; version does not exist. Version has either been pruned, or is for a future block height (latest height: 14026...): invalid request

## Description

When exploring the history of data at a vstorage key, `err.codespace ===
'sdk' && err.code === 38` is sort of the first-class signal for "there
is no more" (_according to what? I'm not sure_). But we don't seem to
always get that sort of error. We have also accepted any error whose
message matches `/unknown request/`. With this change, we also take
`/pruned/` as such a signal.

DRAFT until:

- [ ] is there a spec for these errors that we could / should cite in
this code?
 - [ ] given the cost of a test, is it OK to land this without one?
- [ ] to fully address #9033, is there something on the chain side that
we should fix? or is this enough? That is: should I change "closes" to
"refs"?

### Security / Scaling Considerations

n / a

### Documentation Considerations

If this fix is to-spec, then there are none. Otherwise, perhaps some
disclaimer is in order, at least as a code comment.

### Testing Considerations

A fix normally comes with a test. A unit test would be nice. But this
testing CLI code isn't factored to facilitate unit testing. It kinda
needs a whole running blockchain. So a test is probably more trouble
than it's worth for a ~1 line fix.

### Upgrade Considerations

The change that introduced the symptoms of #9033 was evidently missing
some upgrade considerations.
