Wrong default value for plugin-content-docs docRootComponent

[ultimate]

Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Description

According to https://docusaurus.io/docs/api/plugins/@docusaurus/plugin-content-docs#docRootComponent the default value for docRootComponent is '@theme/DocPage'. However according options.ts of plugin-content-docs the default is '@theme/DocRoot' and it seems that '@theme/DocPage' from docusaurus 2 no longer exists.

Self-service

• I'd be willing to address this documentation request myself.
