Sometimes Joomla 4 shows there is an update for the "Installer - Install from Web" extension, but when you try to update it you end up getting a "PLG_INSTALLER_WEBINSTALLER_ERROR_PLUGIN_INCLUDED_IN_CORE"
error.
This video shows a fix for this issue.
The full text of the error message that you get on the screen
Extension Update: Custom install routine failure.
Before updating ensure that the update is compatible with your Joomla! installation.
You are strongly advised to make a backup of your site's files and database before you start updating.
