Make release candidate of ShapeShift Snap

[willyogo]

The final version of MM Flask with the v1 Snaps API is 10.29

Consensus asked us to grab the build here and use it to make a release candidate:
https://app.circleci.com/pipelines/github/MetaMask/metamask-extension/41610/workflows/84c03d93-3b9c-476d-bf76-a43585a90e21/jobs/1159003/artifacts

Note: 10.29 is the latest flask version to use MetaMask/snaps#1364

After that, they will schedule a Gap Audit with Conensys Diligence and add the snap to the allowlist.

AC:

1. A release candidate of the snap is made using MM Flask version 10.29
2. The release candidate is sent to [email protected]

More context from Montoya:
April 5th, 2023:
Hi Willy, the final version of Flask with the v1 Snaps API is 10.28.1. It will be hitting the extension stores soon but in the meantime you can grab the build here and use it to make the release candidate of the ShapeShift snap: https://app.circleci.com/pipelines/github/MetaMask/metamask-extension/41610/workflows/84c03d93-3b9c-476d-bf76-a43585a90e21/jobs/1159003/artifacts

Then I will schedule a gap audit with ConsenSys Diligence and once that is done we can get you into our allowlist.

Hi ShapeShift team!

You can now use the publicly available release of Flask to prepare your release candidate, 10.28.2: MetaMask/snaps#1348

Please make sure that the snaps CLI is on version 0.30.0 when building.

If you run into any errors, it may be due to some bugs with built in packages that have surfaced in this build. Just let me know and I can check with my engineering team.

May 1, 2023 (in response to "When should we aim to have this done by?"):
I have Diligence on hand ready to do another audit as soon as you have it updated for Flask 10.29, so the sooner the better!
