Cannot install old versions of Linkerd (-amd64 suffix is missed)

Bug Report

What is the issue?

Installation script was changed in a way it is impossible to install old versions.

How can it be reproduced?

ENV LINKERD2_VERSION=stable-2.7.1
RUN curl -sL "https://run.linkerd.io/install" | sh

Logs, error output, etc

linkerd check output

Environment

Docker

Possible solution

There should be a flag to support old versions, but I don't see any in the install script.

Workaround:

ENV LINKERD2_VERSION=stable-2.7.1
RUN curl -L https://github.com/linkerd/linkerd2/releases/download/${LINKERD2_VERSION}/linkerd2-cli-${LINKERD2_VERSION}-linux --output /usr/local/bin/linkerd \
  && chmod +x /usr/local/bin/linkerd
