Support typescript-eslint v8 to use the Project Service

[Samuel-Therrien-Beslogic]

See https://typescript-eslint.io/blog/announcing-typescript-eslint-v8#project-service

As a temporary workaround, I'm still setting EXPERIMENTAL_useProjectService:

/** @type {import("eslint").Linter.Config} */
module.exports = {
  parserOptions: {
    projectService: true,
    // Still needed for plugins that haven't updated to typescript-eslint@8 yet
    EXPERIMENTAL_useProjectService: true,
  },
}

@Samuel-Therrien-Beslogic how did you solve this error

Error while loading rule 'etc/no-deprecated': You have used a rule which requires parserServices to be generated. You must therefore provide a value for the "parserOptions.project" property

[Samuel-Therrien-Beslogic]

@last-Programmer depends on the exact version of typescript-eslint you have:
Either use the god old https://typescript-eslint.io/packages/parser#project
Before v8 you can try EXPERIMENTAL_useProjectService instead of https://typescript-eslint.io/packages/parser#projectservice

I have this

    "@typescript-eslint/eslint-plugin": "8.8.0 || eslint - typescript rules",
    "@typescript-eslint/parser": "8.8.0 || eslint - typescript code parser",

        languageOptions: {
            ecmaVersion: 2022, // Allows for the parsing of modern ECMAScript features

            parser: parserTsEslint, // Specifies the TS ESLint parser
            sourceType: "module",
            parserOptions: {
                projectService: true,
                tsconfigRootDir: import.meta.dirname,
            }
        },

still getting the error with eslint 9

[last-Programmer]

@Samuel-Therrien-Beslogic i tried with EXPERIMENTAL_useProjectService: true,. The same error is happening for the following rules in eslint 9. with eslint 9 i need to use npm install --force to install this plugin otherwise it npm install fails.

            //"etc/no-const-enum": "error",
            //"etc/no-deprecated": "error",
//"etc/no-internal": "error",
//"etc/underscore-internal": "error",

Sorry I'm not using ESLint 9 yet. I still have too many plugins that don't support yet. It's possible you're hitting more unresolvable version ranges than I am.
This issue is about typescript-eslint v8. Feel free to open a new one for ESLint 9 support if that's lacking.
Edit: Just saw you did 😄 #74
