WebGLRenderer: Use working color space for render targets.

[Mugen87]

Fixed #33030.

Description

Instead of hardcoding LinearSRGBColorSpace as the working color space for render targets, it's more correct to use ColorManagement.workingColorSpace. This will retain the color space configuration from webgl_test_wide_gamut and post processing works as expected.

Sidenote: We already use ColorManagement.workingColorSpace for transmission render targets so this change makes the code in WebGLRenderer more consistent.
