Suggestion: use actions/cache to cache the install of neonctl

This would save about 10s per run.

Hey!
I've tried caching npm cache directory and global node_modules and it didn't affect the npm i -g neonctl command duration. But the actual caching took 2m30sec!
Anyway, I think rewriting this project in JavaScript will also give it free caching capabilities.

Here is a link to te workflow run https://github.com/duskpoet/test_neon_gha/actions/runs/10670278254/job/29573964907

@duskpoet try doing something like:

      - name: Install Neon CLI
        run: |
          if ! command -v neonctl &> /dev/null; then
            npm install --global neonctl@latest
          else
            echo "Neon CLI is already installed"
          fi

Also maybe the v4 action instead of v3?

This way we won't pick up the newest CLI version when it's released
