Live Preview: support URL tooltips

Steps to reproduce

  1. Create a link with a tooltip
    Example:
    [example](https://example.com "tooltip text")
    
  2. Enter live preview mode if you are not in it already
  3. Move your cursor to a different line so it renders as a link instead of markdown
  4. Hover over link. There should be tooltip, but there isn’t.
  5. Switch to reading mode.
  6. Hover over link. The tooltip appears as it should.

Expected result

Tooltip containing text in inverted commas after link href to appear when link is hovered in live preview mode, as it does in reading mode.

Actual result

No tooltip appears, as the span that contains the link alias does not contain a title attribute with the tooltip text.

Additional information

This can be fixed by adding a title attribute to the span.cm-link element containing the tool-tip text.

It might make more sense for the tooltip created by obsidian that shows the href for a link when in reading mode to be replaced by the user defined tooltip text if there is any.

This is what it looks like when a link is hovered in reading mode (the cursor disappears when I take a screenshot):
