Iss1958 - Update GH workflows to support release process

[jadecarino]

Why?

• Last week I added a workflow_dispatch inputs context so that when someone kicks off the main build chain with a workflow_dispatch either for a release build or development branch build, they can choose the values for if jacoco is enabled (should be for main builds) and if signing should be enabled (should be for main or release builds).
• These inputs were used in the workflow and correctly received the values if triggered by a workflow_dispatch.
• However, if the build was triggered from a push to main (normal main build) these inputs would be blank so would have a null value if used.
• I've added duplicate steps where one is used on workflow_dispatch and uses the input values and the other is on push and uses the default values/command.
