fix: broken imports in esm + typescript <5.5

[JasonWeinzierl]

import * as ts from "typescript" does not work as expected in ESM until TypeScript 5.5 (see https://devblogs.microsoft.com/typescript/announcing-typescript-5-5/#easier-api-consumption-from-ecmascript-modules). This was causing projects using an ESM eslint config with TypeScript 4.7 through 5.4 to get:

Oops! Something went wrong! :(

ESLint: 8.57.1

TypeError: Cannot read properties of undefined (reading 'Any')

This changes to import ts from "typescript" so the import works on those older TypeScript versions in ESM.

• Also increase minimum TypeScript version to 4.7.4 to align with typescript-eslint/typescript-estree's supported versions.
