Default 'version' should be the tag version

[lazerwalker]

This means that the "Game configuration" section should have access to an env variable containing the current 'version'.

This means that the "should we autogenerate a tag?" logic needs to come earlier, and it may be finally time to consolidate it to be less janky (i.e. remove the step where we have slightly-different versions of the same action based on a conditional)
