Typescript file should have union of string literal types, not just generic string types #551
Description
The types via node_modules/bowser/index.d.ts aren't extremely useful
Most variables are just string rather than explaining what the actual values could be (eg 'MacOS' | 'Windows' or 'macos' | 'windows')
I believe the source code probably has explicit values for these, and that the types could be defined better:
const BROWSER_MAP: Record<string, string>;
const ENGINE_MAP: Record<string, string>;
const OS_MAP: Record<string, string>;
const PLATFORMS_MAP: Record<string, string>;
