feat: Allow specifying '1' for height in copyable text to fill the remaining space

[marek-mihok]

Updated API description:

export interface CopyableText {
  /** Text to be displayed inside the component. */
  value: S
  /** The text displayed above the textbox. */
  label: S
  /** An identifying name for this component. */
  name?: S
  /** True if the component should allow multi-line text entry. */
  multiline?: B
  /** Custom height in px (e.g. '200px') or use '1' to fill the remaining card space. Requires `multiline` to be set. */
  height?: S
}

Closes #1823

Thanks @marek-mihok. A couple of changes are needed.
