ci: remove windows transparent vlan conflist

[QxBytes]

Reason for Change:

Multitenancy swiftv1 transparent-vlan mode is only supported on linux, so the windows conflist is no longer needed and should not be included in the cni image. The azure-multitenancy-transparent-vlan.conflist in the cni image will now always be the linux azure-multitenancy-transparent-vlan conflist.

Issue Fixed:

See above

Requirements:

• [X] uses conventional commit messages
• [ ] includes documentation
• [ ] adds unit tests
• [X] relevant PR labels added

Notes: Successful image build only: https://msazure.visualstudio.com/One/_build/results?buildId=107986351&view=results
