linkifyText throws a DOMException if a link is inserted inside a text node

[ganthern]

• open Demo.html
• open DevTools
• type "ww" into the text editor
• press the left arrow key once
• type a space
• type "www.google.com"
• type another space
• see the error pop up in the console:

the reason are the following lines: https://github.com/fastmail/Squire/blob/a8cd95a688cb5c974528dd80b92017a81a55f62d/source/keyboard/KeyHelpers.ts#L127-L133

I'm not sure what the exact bug is here.
