Update metadata Umi tests

[danenbm]

Adding the following Umi tests, ported from existing js-solita tests:

• can update the metadata of a minted compressed NFT
• can update metadata using the getAssetWithProof helper
• cannot update metadata using collection update authority when collection not verified
• can update metadata using collection update authority when collection is verified
• cannot update metadata using tree owner when collection is verified

I just had to add the proof alias to the kinobi config, but other things such as the UpdateArgsArgs that has defaults is already set up.

A few more test cases on the way.

Replacing this PR with #70 as this has too many merge conflicts after merging update-metadata-staging into main.
