All of the changes to the files in docs/content/docs/reference/components/ are not acceptable.

Each component description must be unique and must accurately describe the actual component and its functionality.

Additionally, every component_vx.mdx file is auto-generated and must not be edited directly, as any changes will be overwritten.
To make persistent changes to a component_vx.mdx file, you must update one of the following sources instead:
README.mdx or ComponentHandler.java
