Distribute deb package via apt.releases.hashicorp.com

[yermulnik]

Given Boundary-UI releases are published to https://releases.hashicorp.com/, which is auto(?)-synced with apt.releases.hashicorp.com, it would be beneficial for Linux users, who rely upon Debian packaging system (Debian, Ubuntu, and simialr), if https://apt.releases.hashicorp.com provided releases for Boudary-UI too.

At the moment the only(?) option for Linux users is to watch this repo's releases and download/install manually when new release is published. This can be managed in a better way 🙏🏻

Thanks in advance.
