v4.5.10 release

Release date: November 1, 2022

v4.5.10 had 24 bug fixes, one new feature, and four improvements.

Significant new features

The Styleguide build command has a new option that allows for a continuous integration pipeline. The option is -p puppeteer-custom-config.json. The contents of puppeteer-custom-config.json override the standard Styleguide build configuration. A typical command is as follows:
```
yarn node node_modules/@brightspot/styleguide/build/bundle -b build/styleguide -o build/theme.zip -p puppeteer-launch-config.json
```

Significant improvements

Enhanced accessibility in various Brightspot forms and widgets.
- Search filters now have the aria-labelledby attribute to describe the inputs.
- Keyboard shortcuts are available for editing images and videos.
- The focus order of the items in the navigation area are now sequential.
- In the image and video editing UI, the crop feature now has a proper name, role, and value.
- Individual projects can customize the purpose of each input field.
- Tabs remain tabs in smaller resolutions instead of turning into a menu.
- Increased contrast between separators and items in a list.
- Buttons in the header now have visible focus.
- Clear identification of multiple languages, such as mixed English and Spanish, in the rich-text editor.
Ensured that Styleguide builds invalidate the browser cache so that after five minutes the server delivers the latest assets.
In board view, editors can now abort a drag-and-drop action by returning the dragged card to its initial column.
Improved the MarkedText schema in GraphQL.

Breaking changes

The schema for the CDA and rCDA have changed, and the following elements have been removed:

interface Mark—removed
type HtmlMark—removed
type MarkedText—removed
type RichTextMark—removed

For the rCDA, there is an option for backwards compatibility in the form of a Use Marked Text Schema V1 toggle field in the Advanced tab of Recordable API schema settings.

For the regular view CDA, this is a breaking change with no backwards compatibility.
