Links: Update LinkTo component

[tmeasday]

Fixes #9502 (at least for LinkTo).

What I did

1. I updated LinkTo and the SELECT_STORY event to take title/name (in addition to) kind/story.
2. I change the href that the LinkTo component to strip the iframe.html, so it behaves sensibly when you cmd click or copy the URL.

What I didn't do

Update the API to take of={}. This would be a natural evolution but now is not the time to do that.

How to test

Add to a docs mdx file:

import LinkTo from '@storybook/addon-links/react'

<LinkTo title="Example/Header" name="Logged In">Header</LinkTo>

Try:

1. Clicking normally
2. Cmd clicking
3. Copying the URL.
