Improve dev-wallet release process

[gregsantos]

There is a need to improve and automate the release process of dev-wallet + CLI

These repos are coupled and need a clear process for updates and releases that doesn't lead to mismatch errors

• [ ] Add changesets and automated release
• [ ] Github actions to export static site and zip for use with CLI gh action
• [ ] Deprecate or test and refine Docker run https://github.com/onflow/fcl-dev-wallet/issues/75
• [x] CLI/Kitty Items notifs on new releases of dev-wallet (?)

Thanks for this, I think testing is lacking much. Last few versions were mostly problematic.

Just a note, the zip will always need to be in version control because that is where Go modules® expects it.
