Rename 3d materials

PR Description:

• "Realistic (Phong)" -> "Legacy (Phong)"
• "Realistic with Textures (Phong)" -> "Legacy with Textures (Phong)
• "Physically Based" -> "Physically Based (Metal/Rough)"
• "Physically Based with Textures" -> "Physically Based with Textures (Metal/Rough)"

these names better reflect their uses, and clearly push users away from the phong materials.

Also reorganise so that the legacy phong materials show last in the drop-down lists.

@DelazJ Could we remove 'good first issue' label? Currently, we have not documented new shading type (physically based & physically based with textures) completely. This could create confusion for newcomer, given that we don't have that yet in our documentation. Anyway, I am also working on that so I believe this should be part of my 3D assignments.
