V15: Add a button to clear schedule

[iOvergaard]

Description

Fixes AB#45942

• Adds a button to clear a set schedule.
• Adds a text if a schedule has changed.
• Removes an unused old body for emails of scheduled content

How to test

1. Schedule a document and try to set a schedule
2. Try to clear the schedule
3. Test that the text does not show up unless there are changes

Tested out, all good, except that I noticed if a document has existing scheduled publish/unpublish dates, then the remove button doesn't appear. I've added commit 4f4183a to fix that. 👍

One thing to mention, with the refactor of the <umb-input-date> component, I'm wondering whether we need that component anymore? As the uses within the CMS can be resolved by using <uui-input> directly. Of course, we would deprecate it first. 😀

We should not throw it away just yet. It sets a standard and overrides what types you are allowed to define. Also, it more easily allows you to target date-specific inputs.

A consideration I had was to keep the internal uui-input and add the appended Clear-button in the component directly instead. That would give a more unified look wherever the component is used. It wouldn't allow you to specify slots from the outside, but if you needed that, you could use the uui-input directly. What do you think about that?

I'd be happy with this approach. Gives a consistent experience for date/time inputs. 👍
