Fix - Edit SAlert icon computation

[VladislavPopovSR]

Motivation:
Current SAlert implementation has warning because of the status icon computation.

Now, we will use it's implementation instead of itself.
Instead of using eagerComputed

const StatusIcon = eagerComputed(() => STATUS_ICONS_MAP[props.status])

We will use native Vue watshSyncEffect

const StatusIcon = shallowRef<Component>()

watchSyncEffect(() => {
  StatusIcon.value = STATUS_ICONS_MAP[props.status]
})

Warning resolved✅
By the way, in Vue 3.4+ native computed was greatly improved and later we can replace every eagerComputed usage with it.
