[BITV] Add title to ActionLink component

[JuliaKirschenheuter]

Problem

To show a tooltip on a ActionLink we currently use v-tooltip. An example can be found in the files_sharing app: https://github.com/nextcloud/server/blob/master/apps/files_sharing/src/components/SharingEntryLink.vue#L46.

v-tooltip is not accessible and we want to migrate to native tooltips (title attribute) instead. An overview can be found in nextcloud-libraries/nextcloud-vue#2503. Main issue could be found in files_sharing app: #35654.

Solution

Add a title prop to the ActionLink component that will render as title attribute on the HTML element.
