chore: disable issues and direct ppl to web-components repo [skip ci] (…

…#162)

All component-related issues (for any version of the component) should be opened either in the web-components monorepo (if it's reproducible with TypeScript and HTML, without Vaadin Flow / Java), or in the flow-components monorepo (if it's about the Java API).
This repository remains open only to be able to release fixes for the versions of this web component used with Vaadin 10, 14 and Vaadin 19 for as long as they are maintained.

In order to make this clear for users, this PR
 - updates the README to make the role of this repo and it relationship with the web-components monorepo very clear
 - disables new issues in this repo: any attempt to create a new issue here would direct the users either to the web-components or to the flow-components monorepo
