Also export tooltip options

[raimund-schluessler]

This adds an export of the tooltip options object, so one can customize the tooltips if necessary.

Works like this:

import { options as TooltipOptions } from '@nextcloud/vue/dist/Directives/Tooltip'
TooltipOptions.container = '#content-vue'

Closes #2993.
