[docker] remove (redundant) chmod and testable workflows (#1710)

## Description
* Removes the redundant `chown` from step 12, relying on the final one
in step 20.
* Adds new workflow inputs
  * guild_deploy_branch which defaults to master
  * testing which defaults to false
* Conditional logic on the push operation
  * If branch is master and testing is false, the push will occur.
  * If branch is master but testing is true, the push will not occur
* If branch is NOT master, but testing is falase, the push will not
occur (prevents mistaken test from updating the public images).

## Where should the reviewer start?
Compare the two builds. Try a workflow dispatch with testing true, and
with branch not set to master.

## Motivation and context
An error in build process when no shell scripts exist in
`/home/guild/.scripts/` when the operation occurs. Allows testing of the
branches for docker building similar to pre-merge testing of changes to
guild-deploy.sh etc.

## Which issue it fixes?
Closes #1709

## How has this been tested?
Local build, and [workflow
job](https://github.com/cardano-community/guild-operators/actions/runs/6996999037/job/19033480048)
