action fails if packer already exists on the machine

[gustavlasko]

If the setup-packer action is run and the agent already has packer installed, the step fails without providing any useful context.

Expected Behavior

I would expect the step to detect that the end result of the action has been acheived (i.e. the requested packer version is present on the agent) and the step succeeds

Current Behavior

Run hashicorp/setup-packer@v3
Installing packer:1.11.1 and adding it to GitHub Actions Path

## Steps to Reproduce

1. Create a github action that targets a runner with Packer installed
1. Call the setup-packer@v2 action
1. Execute your action

Hi @gustavlasko, thanks for reporting this!

Do you have a link to an Actions log where you encounter this? Alternatively, a workflow .yml would also work!
