[Feature Request] Reinstate `curl | sh` installation

[dandavison]

The CLI server is the most convenient way to run a server for prototyping and in CI. It should have simple curl | sh as an installation option, as is very common among comparable CLI tools. This is particularly convenient and appropriate when installing in a Dockerfile.

(I notice GitHub's CLI uses webi; perhaps that's worth investigating.)

We should also consider publishing in package managers which also makes it convenient when installing in a Dockerfile for most common distros

[dandavison]

That's significantly less convenient -- often you're starting from a base image, and often nowadays that's a specialized minimal distro, and application developers who are just trying to use Temporal in a docker compose project can't be expected to be familiar with the package manager in these distros.
