title: How to update the configuration for eslint after upgrade angular 9 to 10
body: <p>After upgrading angular from 9 to 10 and run <code>npm run lint</code>, I got this
  experiment
  &gt; ng lint --fix</p>
  <pre><code>Schema validation failed with the following errors:
    Data path &quot;&quot; should NOT have additional properties(tsConfig).
  </code></pre>
  <p>My angular.json is:</p>
  <pre><code>    ...&quot;lint&quot;: {
        &quot;builder&quot;: &quot;@angular-eslint/builder:lint&quot;,
        &quot;options&quot;: {
          &quot;eslintConfig&quot;: &quot;.eslintrc.js&quot;,
          &quot;tsConfig&quot;: [
            &quot;tsconfig.app.json&quot;,
            &quot;tsconfig.spec.json&quot;,
            &quot;e2e/tsconfig.json&quot;
          ],
          &quot;exclude&quot;: [&quot;**/node_modules/**&quot;]
        }
      },...
  </code></pre>
  <p>Here is my package.json - devDependencies:</p>
  <pre><code>...&quot;@angular-devkit/build-angular&quot;: &quot;~0.1001.1&quot;,
  &quot;@angular-eslint/builder&quot;: &quot;0.3.0-beta.1&quot;,
  &quot;@angular-eslint/eslint-plugin&quot;: &quot;0.0.1-alpha.32&quot;,
  &quot;@angular-eslint/eslint-plugin-template&quot;: &quot;0.0.1-alpha.32&quot;,
  &quot;@angular-eslint/template-parser&quot;: &quot;0.0.1-alpha.32&quot;,
  &quot;@angular/cli&quot;: &quot;~10.1.0&quot;,
  &quot;@angular/compiler-cli&quot;: &quot;~10.1.1&quot;,
  &quot;@angular/language-service&quot;: &quot;~10.1.1&quot;,
  &quot;@types/file-saver&quot;: &quot;^2.0.1&quot;,

  &quot;@typescript-eslint/parser&quot;: &quot;2.31.0&quot;,
  &quot;codelyzer&quot;: &quot;^5.2.2&quot;,
  &quot;eslint&quot;: &quot;^7.6.0&quot;,
  &quot;eslint-config-airbnb-typescript&quot;: &quot;^8.0.2&quot;,
  &quot;eslint-config-prettier&quot;: &quot;^6.11.0&quot;,
  &quot;eslint-plugin-import&quot;: &quot;^2.21.2&quot;,
  &quot;eslint-plugin-prettier&quot;: &quot;^3.1.4&quot;,...
  </code></pre>
  <p>when I replace 'tsConfig' with 'lintFilePatterns', the cli says:</p>
  <pre><code>error  Parsing error: &quot;parserOptions.project&quot; has been set for @typescript-eslint/parser.
  The file does not match your project config: tsconfig.app.json.
  The extension for the file (.json) is non-standard. You should add &quot;parserOptions.extraFileExtensions&quot; to your config
  </code></pre>
  <p>What should I update?</p>
