We could also just say to set eslint as the default validator:

"eslint.validate": ["typescript", "typescriptreact", "javascript"]

I haven't verified the setting you pasted, but I've added it to the PR.
I personally had this in my global settings:

    "[javascript]": {
        "editor.defaultFormatter": "dbaeumer.vscode-eslint"
    },
    "[typescript]": {
        "editor.defaultFormatter": "dbaeumer.vscode-eslint"
    },

I wonder if these settings could go into the .vscode/settings.json file instead?

That sounds like an even better idea.
