Decommission the 'Quote' standalone component

User Story

None

Description

The Quote component is no longer required. This is because a quote can be created within a Content component and it’s not necessary to have two ways of creating the same feature.

The Quote component also has a defect when used on a page without a side navigation (no left padding). The quote within the content component does not have this defect.

We also need a solution for users who are currently using the quote component. The quotes can’t ‘disappear’ and ideally are converted into a quote within a content component.

Acceptance Criteria

AC 1 - available components
Given I’m an authenticated user
When I open the component dropdown to select a component to use
Then I do not see a Quote component option

AC 2 - Existing sites using the ‘Quote' component
Given I’m a user of an existing CivicTheme site
When I check any pages that have used the Quote component
Then I see my content still having a styled quotation

Solution Direction

1. Remove Quote component: configuration, template, preprocess
2. Create an update hook to convert a quote component to a content component with a `

` markup and content from the Quote component within it.
3. Create a test for an update hook to test that the component can be removed and the database can be updated.

The UIKit needs to support citations residing within the `

` component markup.
