Media: Accessibility: Fix labels in scale tool.

The field for setting width in the media editor scale inputs had an incorrect label. Additionally, both the width and height labels had extraneous adjectives describing the fields. These are not necessary given the `fieldset` and `legend` providing context.

Change the 'width' label from 'scale height' to 'Width'. Change the 'height' label from 'scale height' to 'Height'.

Fixes #65685.
