Prepare snap for publication

[damip]

What we need to publish the snap is defined in https://docs.google.com/forms/d/e/1FAIpQLSeDAnk0Di_k8Qgrsj9_ofnf-1d_NfbG3fmSOHD1m8dKun1pXw/viewform .
Everything will be handled by the foundation, except:
- Snap Name (This must match the proposedName from the snap.manifest.json file. It should not contain the word "snap". This is the name displayed in the Snap Directory).
- Snap Website - URL (This is the official Companion dapp or Landing page for your Snap. Users will go here to interact with your Snap and learn more about it. If your Snap does not need a website, leave this blank.)
- Please provide the URL to your npm package.
- Please provide the Snap Version number that is to be allowlisted. (It should match the version in the Snap's package.json and snap.manifest.json files. If your Snap was audited, it should match the version in the audit report.)
- Has the Snap's Manifest been verified against the simulator? (If the Snap is not verified, it will not be allowlisted. In the simulator, update the link at the top-right of the page to your npm url and check the correctness of your manifest information.)

TODO: ensure all of that is OK, upload on npm, and give the URLs
