Consistency between Wireframe2d and Wireframe (#14720)

# Objective

- Wireframe plugins have inconsistencies between 3D and 2D versions.
This PR addresses the following
  - 2d version uses `Srgba` for colors, 3d version uses `Color`.

  
## Solution

- This PR brings consistency by doing the following change
  - `Wireframe2d` now uses `Color` instead of `Srgba`

## Testing

- `wireframe_2d` and `wireframe` examples were verified and they work as
before.

---

## Migration Guide

- `Wireframe2dConfig`.`default_color` type is now `Color` instead of
`Srgba`. Use `.into()` to convert between them.
- `Wireframe2dColor`.`color` type is now `Color` instead of `Srgba`. Use
`.into()` to convert between them.
