test: add Noble/Penumbra IBC smoke test script (#4937)

## Describe your changes

This adds a test script that performs bidirectional IBC transfers
between Penumbra and Noble.

Prerequisites:

* A Noble account with uusdc funds
* A Penumbra account with UM funds to pay fees
* A checkout of [the Noble SDK](https://github.com/noble-assets/noble/)
* A working `pcli` installation in the `$PATH`
* `jq`

This should be integrated into a GitHub workflow. It's not clear if it
belongs in the existing smoketest workflow or a new workflow.

## Checklist before requesting a review

- [x] I have added guiding text to explain how a reviewer should test
these changes.

- [x] If this code contains consensus-breaking changes, I have added the
"consensus-breaking" label. Otherwise, I declare my belief that there
are not consensus-breaking changes, for the following reason:

  > test only
