Master branch now uses flow-c1 in install-scripts

[NtTestAlert]

The documentation for installing flow-cli refer to master branch install scripts, as do probably a lot of scripts and pipelines.

In a recent merge the renaming of flow to flow-c1 was merged to master, breaking previous functionality and the desired interoperability

(imo master branch should keep the flow exe name, the branches should include flow-c1. idk. it's not very important but breaks backward comp

We should freeze the code and try to avoid another homebrew release until Cadence 1.0 is on the master branch. I believe the install script looks at the releases. I think it would work in its current state. Are you experiencing an issue, or is this forward thinking for the next release if we have one?

The install scripts should install the latest (non-prerelease) version by default, as flow, and have an option to install the latest pre-release version, as flow-c1.

this should let you install the old pre-1.0 binary
