parserOptions was not passed to context

[aladdin-add]

this is from #14622 (comment)

Tell us about your environment

Node version: v16.0.0
npm version: v7.10.0
Local ESLint version: v7.28.0 (Currently used)
Global ESLint version: Not found
Operating System: linux 4.19.128-microsoft-standard

What parser (default, @babel/eslint-parser, @typescript-eslint/parser, etc.) are you using? default

What did you do? Please include the actual source code causing the issue, as well as the command that you used to run ESLint.

let ecmaVersion = null;

linter.defineRule("ecma-version", context => ({
    Program() {
        ecmaVersion = context.parserOptions.ecmaVersion;
    }
}));

linter.verify("", {
    rules: {"ecma-version": 2},
  {parserOptions: {ecmaVersion: 5}},
});

assert.strictEqual(ecmaVersion, 5);

it seems the ecmaVersion is always null.

AssertionError: expected null to equal 5

Are you willing to submit a pull request to fix this bug?

Hmm, I had tried all three tests from #14622 (comment) on aladdin-add:update/ecma-latest and they worked then.

AssertionError: expected null to equal 5

This happens when there's a parsing error, so the rule isn't run and ecmaVersion keeps its initial value (let ecmaVersion = null). Parsing error isn't thrown from linter.verify(), it's in the linting result as a lint message item.

oh, my bad! I just passed the wrong configs.
