[docs] Theme customization docs using different function names than implementation

[joan-teriihoania]

Hello!

Note! This has been created as a mirror to the original issue in the main repository. To which repository this issue belongs to will depends on whather this is a naming issue in the package's implementation, or a documentation typo. For now, I've elected to raise the issue on both.

The documentation states that the following helpers are exported by nativewind/theme:

• platformSelect
• platformColor()
• hairlineWidth()
• pixelRatio()
• pixelRatioSelect()
• fontScale()
• fontScaleSelect()
• getPixelSizeForLayoutSize()
• roundToNearestPixel()

However, at the moment in the nativewind's theme package, only the following are exported:

• hairlineWidth,
• platformSelect,
• pixelScaleSelect,
• fontScaleSelect,
• pixelScale,
• fontScale,
• roundToNearestPixel,
• platformColor,
• getPixelSizeForLayoutSize,

It seems that pixelScale and pixelScaleSelect were used in react-native-css-interop but the docs mention pixelRatio and pixelRatioSelect. This issue is happening on the main branch with the current v4 documentation.

Is this a typo? Or do pixelRatio and pixelScale have different behaviours.
