refactor: Standardize and share store definitions

[aklinker1]

I've also refactored the screenshot endpoints to use a path param for the extension store name and deprecated the old store names. They'll be around for a while, but I introduced some better named ones:

queue/src/enums.ts

Lines 1 to 12 in 8c4f4b7

	export enum ExtensionStoreName {
	ChromeWebStore = "chrome-web-store",
	FirefoxAddonStore = "firefox-addon-store",
	EdgeAddonStore = "edge-addon-store",
	/** @deprecated Use {@link ChromeWebStore} instead. */
	ChromeExtensions = "chrome-extensions",
	/** @deprecated Use {@link FirefoxAddonStore} instead. */
	FirefoxExtensions = "firefox-extensions",
	/** @deprecated Use {@link EdgeAddonStore} instead. */
	EdgeExtensions = "edge-extensions",
	}
