MultiSelect: missing loadingIcon passthrough option in documentation

[goldengecko]

Describe the bug

In the pass through diagram, item 9 is the loading icon. This is missing from the table of options below. This means that all the items below this are incorrectly numbered. Looking at packages/primevue/src/multiselect/MultiSelect.vue:50 it appears that the missing item should be named loadingIcon

I have been trying to work out what needs to be changed to get the styling working converting from v3 styles to v4 styles, and have found that the image in the v4 documentation is incorrect and the mapping from v3 to v4 is a bit complex in part due to replacement of standard elements with components, and in part to some things apparently being undocumented. I have tried to put together a list of items in v4 and where they have come from in v3 so that I can get my head around the updates required for styling.

Hopefully this will be useful in updating the documentation:

• root (value 1)
• labelContainer (value 2)
• label (value 3)
• token -> chipItem (value 4)
• tokenLabel -> pcChip (value 5) (this used to be a separate label, but is now replaced with a Chip component.)
• removeTokenIcon -> Labelled as value 6 on the diagram but no corresponding item in the new configuration since it becomes part of the pcChip settings
• trigger -> dropdown (value 7)
• loadingIcon (undocumented)
• dropdownIcon (value 8)
• panel -> overlay (value 9)
• header (value 10)
• headerCheckbox -> pcHeaderCheckbox (value 11) (contains an icon property)
• filterContainer -> pcFilterContainer (value 12) - (converted from a div to an IconField)
• filterInput -> pcFilter (value 13) - (converted from input to InputText)
• pcFilterIconContainer (value 14) - new item that wasn't there in v3
• filterIcon (value 15)
• closeButton (old value 16) -> no longer there in v4 - appears to be covered by the use of IconField for value 14
• closeIcon (old value 17) -> also covered by the IconField
• wrapper -> listContainer (value 16)
• virtualScroller (value 17)
• list (value 18)
• itemGroup -> optionGroup (value 19)
• item -> option (value 20)
• option -> optionLabel (value 21)
• itemCheckbox -> pcOptionCheckbox (value 22) (contains an icon key)
• emptyMessage (value 23)
• hiddenInputWrapper (undocumented) -> hiddenInputContainer (value 24)
• hiddenFirstFocusableEl (value 25)
• hiddenEmptyMessage (undocumented)
• hiddenFilterResult (value 26)
• hiddenInput (old value 26) -> hiddenInput (undocumented)
• hiddenSelectedMessage (value 27)
• hiddenLastFocusableEl (value 28)
• transition (value 30)
