fix(agoric-cli): wrong URL in agops oracle setPrice, find-continuing-…

…id (#10593)

refs:
 - #10592
 - #10450

## Description

It looks like #10450 changed the URL used to get oracle operator wallet info from

`https://emerynet.rpc.agoric.net:443/abci_query?path=%22/custom/vstorage/data/published.wallet.agoric1ldmtatp24qlllgxmrsjzcpe20fvlkp448zcuce.current%22&height=0`

to

`https://emerynet.rpc.agoric.net:443/abci_query?path=%22/custom/vstorage/data/wallet.agoric1ldmtatp24qlllgxmrsjzcpe20fvlkp448zcuce.current%22&height=0`

This PR uses `readPublished` consistently in order to restore the `published.` prefix.

### Security / Scaling / Documentation Considerations

none

### Testing Considerations

I'm a little surprised that we don't have `z:acceptance` tests that rely on this testing tool.

### Upgrade Considerations

This is client-side only code.
