Add support for eden_version input in test workflow

When the workflow is triggered from the outside, action/checkout
defaults to checking out the latest master which is not always desired.
For better compatibility with older EVE release the user should be able
to specify the version of eden to be used in the test workflow. If no
version is specified, the workflow should resert to the default behavior.
