Render Pipeline Converter - Scan button scans both target pipelines (Universal Renderer and 2D renderer), but it should scan only one that is selected. 

Steps to reproduce:

1. Create a new URP project
2. Open Render Pipeline Converter window (Window > Rendering > Render Pipeline Converter)
3. Checkmark all options ({}Renderer Settings, Animation Clip, Material Reference Converter and Material shader Converter{}). 
4. Change target pipeline from Universal Renderer to 2D Renderer.
5. Press Scan

Observe that even though target pipeline is selected 2D renderer, it still scans Universal Renderer 

Actual results: Scans both target pipelines - Universal Renderer and 2D renderer

Expected results: Scans only the selected target pipeline

Reproducible with versions: 6000.5.0a1, 6000.4.0a3, 6000.3.0.b4, 6000.2.6f2, 6000.1.17f1, 6000.0.58f2, 2023.3.0b10, 2022.3.62f1

Notes: Please be in mind that on different Unity versions the repro is slightly different due to slightly different UI. So, instead of scan button, there's Initialize button.
