Introduce toggleArea slot to ReadMoreText composables

[fornewid]

• Onclik "Read More" is triggered even other words are clicked #41

⚠️ Breaking Changes

onReadMoreClick, onReadLessClick slots are removed.
So, if you are already using this attribute, you need to change your code like this:

foundation:

  val (expanded, onExpandedChange) = rememberSaveable { mutableStateOf(false) }
  BasicReadMoreText(
      text = "text",
      expanded = expanded,
+     onExpandedChange = onExpandedChange,
      ...
-     onReadMoreClick = {
-         onExpandedChange(true)
-     },
      readLessText = stringResource(id = R.string.read_less),
-     onReadLessClick = {
-         onExpandedChange(false)
-     },
+     toggleArea = ToggleArea.More,
  )

material, material3:

  val (expanded, onExpandedChange) = rememberSaveable { mutableStateOf(false) }
  ReadMoreText(
      text = "text",
      expanded = expanded,
+     onExpandedChange = onExpandedChange,
      ...
-     onReadMoreClick = {
-         onExpandedChange(true)
-     },
      readLessText = stringResource(id = R.string.read_less),
-     onReadLessClick = {
-         onExpandedChange(false)
-     },
+     toggleArea = ToggleArea.More,
  )
