Let the release build use signed prebuilds from sim-server repo (#606)

This PR changes the build script we use for simulator server release
builds.

Since in the sim-server repo we have automated action that generates
properly built and signed binaries, we should use that instead of
building release version locally (especially that we need binaries for
all the platforms).

The new script uses github CLI to download the pre-built binaries from
sim-server repo releases, and to work requires that github CLI is
installed and authenticated with an account that has access to the repo.

The script also verifies that the binaries we use for sim-server are
from a tagged version. We do that by checking the tag of sim-server
submodule. This way we get the tag for the release from which we should
download the binaries.

As a consequence, the release builds of the extension can only use a
tagged version of the sim-server (which is good, as would let as keep
better track of the updates done between the two repos).

## Test plan
1. Make release build, make sure it runs ok
