Review plugin development guide to see if it can work for M1

Version

1.13.x (latest stable)

Is your feature request related to a problem? Please describe.

When trying to stand up the now-deprecated hmac-auth plugin, I ran into AMD/M1 compatibility issues.

There is dependency, , documented in our auth plugin development guide that describes a dependency: verify-plugins-linux-amd64: a script to verify that the plugin can be loaded by the given Gloo Edge version. which I believe is the issue.

To reproduce on an M1 Mac, checkout the hmac-auth repository and apply the following diff:

 and follow the setup steps in the readme.

 When you get to the command:
 `make build-plugins GLOOE_VERSION=1.6.2 "DOCKER_BUILD_ARGS=-t gcr.io/solo-test-236622/hmac-plugin:test"`

 you will get (or at least I get) the error:

Describe the solution you'd like

Validation/investigation by another developer and an assessment of the level of effort needed to make plug-ins and the documentation available on all architectures.
