Theme Link processing opt-out is not working as expected

Problem/Motivation

CivicTheme has a `components.link` opt-out.

This is expected to in the code to opt out from adding CivicTheme link classes to anchors and converting URLs to anchor tags.

This is not the case, this is controlled on converting URLs to anchors is controlled in text_format not theme settings.

Steps to reproduce

1. Opt out from Link processing (`components.link`) in theme settings
2. Add a content component and add a URL and an email (not an anchor)
3. View page and see that the URL and email are now links - `civictheme_rich_text` has default set to convert URLs and emails to anchor tags
4. However, the CT link classes should not have been added to the anchors with this opted out.

Proposed resolution

No code change just communication of expectation.
