Flat config with ESM modules doesn’t work

[cherryblossom000]

Bug Report

Rules such as functional/type-declaration-immutability don’t work when using the flat config with ESM modules.

test.ts:

type Test = readonly string[]

eslint.config.js:

import tseslint from 'typescript-eslint'
import functional from 'eslint-plugin-functional/flat'

export default tseslint.config(
	{
		files: ['**/*.ts'],
		languageOptions: {
			ecmaVersion: 2022,
			parserOptions: {
				project: true,
				tsconfigRootDir: import.meta.dirname,
			},
		},
	},
	tseslint.configs.base,
	functional.configs.strict,
	{
		rules: {
			'functional/type-declaration-immutability': 'error',
		},
	},
)

Expected behavior

No errors.

Actual behavior

/path/to/file/test.ts
  1:1  error  This type is declare to have an immutability of at least "Immutable" (actual: "Unknown")  functional/type-declaration-immutability

Steps to reproduce

1. Install eslint-plugin-function@6.2.0-next.3
2. Run eslint test.ts

Proposed changes

eslint-plugin-functional/src/utils/conditional-imports/typescript.ts

Lines 3 to 9 in 72c6f67

	export default (() => {
	try {
	return require("typescript") as typeof ts;
	} catch {
	return undefined;
	}
	})();

typescript can’t be imported in an ESM module as require is not defined.
