Updated Node Red to v3.1.0 and found a problem with the dark mode theme I have used forever looking wrong. Example below, the background is now white instead of dark same as the palette:

I'm using Node Red in a Docker container and this is the theme:
No longer supported.
Node Red logs show this problem so it looks like I'm running an older version, how can I fix that please?
1 Nov 19:20:26 - [debug] Module: @node-red-contrib-themes/midnight-red 1.5.2 /data/node_modules/@node-red-contrib-themes/midnight-red
1 Nov 19:20:26 - [debug] ! Module: @node-red-contrib-themes/midnight-red 2.2.3 /usr/src/node-red/node_modules/@node-red-contrib-themes/midnight-red *ignored due to local copy*
Here's the end of my settings.js file which does not match the new format, but I think I need to make sure I'm using 2.2.3 first before changing.
// Customising the editor
editorTheme: {
projects: {
// To enable the Projects feature, set this value to true
enabled: false
},
page: {
css: "/usr/src/node-red/node_modules/@node-red-contrib-themes/midnight-red/theme.css"
}
Or maybe Node Red already supports dark mode nowadays and I don't need the theme at all?
I'm not that up to date due to life and don't really want to break anything just now if that makes sense.
