Add post-job step for cleaning temp dir

Description

By default, setup-terraform action is downloading terraform file to temporary directory. It should be cleaned in the self-hosted runners because it gets cluttered with unused file with time.
Also, I can't set condition into action.yaml to runs.post-if directive due to issue

Changes Made

• Added support post-job step for cleaning temporary directory for terraform bin file.

How to Use

1. Set parameter cleanup_workspace.

Example workflow configuration:

steps:
- uses: hashicorp/setup-terraform@v3
  with:
     cleanup_workspace: true
