Admin reskin: Remove line-height from input elements. Fixes #64763.

[ArkaPrabhaChowdhury]

This change removes the redundant line-height property from text-based admin input elements in src/wp-admin/css/forms.css.

The height of these elements is already sufficiently handled by the min-height property (40px for standard inputs and 32px for compact inputs), making an explicit line-height unnecessary and potentially problematic for certain font-rendering scenarios.

With regards to the previous patches in this ticket, this PR also removes the line height in the reported search bar as seen below:
