Fix CI scripts

[Shane32]

Updates CI scripts as follows:

• Bumps windows-2019 to windows-latest due to:
  • The Windows 2019 Actions runner image will begin deprecation on 2025-06-01 and will be fully unsupported by 2025-06-30 actions/runner-images#12045
• Changes expected folder from D:\a\qrcoder\qrcoder to ${{ github.workspace }} (due to it actually being C:\a\qrcoder\qrcoder now)

@codebude Think we could merge this in?

Hi @Shane32 ,

since QRCoder will reach its end of life and the repository will be archived on November 1st, 2025, I’d like to clarify how to proceed with this PR.

Would you prefer me to merge it before the archival, or should I close it instead?
Please let me know what you think – I want to handle your contribution in the way that feels most appropriate to you.

Thanks again for your effort and contribution!
