Olivero: Enable user generated title within Syndicate block (when core issue is fixed)

Problem/Motivation

Having installed beta1 and implemented the RSS Feed link in the social bar, I’m finding it working well (at least, once #3048848: Syndicate block outputs wrong feed URL → is used).
However, given that any particular taxonomy vocabulary view might have it’s own RSS feed, is the title “RSS feed” really descriptive enough?

See desktop:

But especially on a mobile device:

There is some confusion of which feed is which.

Steps to reproduce

Create a taxonomy view and look at the bottom. Or just look at the bottom of my example: https://rachelnorfolk.me/topics/motorbike

Proposed resolution

Change the block text “RSS Feed” to say “Site RSS Feed” or some other, clear, description.

Remaining tasks

Agree on the the title for the site RSS feed
