Describe the bug:
On the exceptions page the download icon looks similar to a share icon

Kibana/Elasticsearch Stack version:

v 7.16.1

Original install method (e.g. download page, yum, from source, etc.):
Eden

Current behavior:

Clicked the share icon expecting to be able to share the list, but was asked to download the list.

Expected behavior:

Change the icon to a download icon. We should think about if we're adding this so that users can actually share the list, if that's the case we should make it easy for them to share and not force them to download the list. If there are technical limitations around sharing, (maybe because lists don't have unique URL's in the app?) we should make it clear to users that they need to download the list then share it.

The aria-label="Export exception list" suggests that this is about downloading the list rather than sharing.
