Update cspell config

[XhmikosR]

@coliff does this still work for you? I don't use cspell through a code editor.

heya - happy new year :-) - yes, I've just tested the .cspell.json config in this PR and it works well with VS Code with https://marketplace.visualstudio.com/items?itemName=streetsidesoftware.code-spell-checker installed. 👍

I wonder, if we just go with en-US, will that mean that only US English will be enforced? We already follow US English, so this might be a good change.

don't know enough about the technical side here, but the removal of extra words and the tweaks to docs look fine to me

It seems there's a gitignore config option we could use too, not sure if it's enabled by default and I can't figure it out from their docs.

It seems there's a gitignore config option we could use too, not sure if it's enabled by default and I can't figure it out from their docs.

Found this in the v5.12.0:

/**
 * Tells the spell checker to load `.gitignore` files and skip files that match the globs in the `.gitignore` files found.
 * @default false
 */
useGitignore?: boolean;

It was specified in their cspell.schema.json:

"useGitignore": {
    "default": false,
    "description": "Tells the spell checker to load `.gitignore` files and skip files that match the globs in the `.gitignore` files found.",
    "type": "boolean"
},

In the current source code it is still false by default.
The value could be switched in a next version. It was supposed to be done in v5.13.0 apparently. Don't know if it has been abandoned or forgotten.
