[input-group] - inconsistent Variable Naming Between Schema and Exposed Component Variables In the schema

[desig9stein]

Since the schema variables are not exposed to the end user, anyone trying to create a custom theme using the schema variable names (e.g., search-resting-elevation) will encounter errors. On the other hand, using the exposed variables (e.g., search-resting-shadow) currently has no effect, which leads to confusion and failed customizations.

Schema props

search-resting-elevation,
search-hover-elevation,
search-disabled-elevation,

However, in the component we expose to the end user:

search-resting-shadow,
search-hover-shadow,
search-disabled-shadow,

Suggested Solution
We should migrate the variable to align with the schema by renaming:

search-resting-shadow → search-resting-elevation
search-hover-shadow → search-hover-elevation
search-disabled-shadow → search-disabled-elevation

This would ensure consistency between the schema and the exposed variables and allow users to customize reliably.
