Links in Markdown/Rich Text lists breaks formatting

[alexrudd]

Describe the bug:

Including a link at the end of an element in a list breaks the formatting when rendered:

* [List item one](https://item1.com)
* [List item two](https://item2.com)

To Reproduce:

Steps to reproduce the behaviour:

1. Create an application that uses the NewRichTextFromMarkdown widget
2. Pass in the markdown from above
3. Run the app and see the bug

Screenshots:

Example code:

package main

import (
	"fyne.io/fyne/v2/app"
	"fyne.io/fyne/v2/widget"
)

func main() {
	a := app.New()
	w := a.NewWindow("Hello World")

	w.SetContent(widget.NewRichTextFromMarkdown(`
# Reproduce list bug

* [List item one](https://item1.com)
* [List item two](https://item2.com)

## Workaround using fullstops

* [List item one](https://item1.com).
* [List item two](https://item2.com).

## Without links

* Item one
* Item two
`))
	w.ShowAndRun()
}

This is also the same thing for normal URL widget when placed in a VBox for example (the underline continues until the end)

But that isn't a break in the formatting or layout - the line literally has that much space left so the Hyperlink is asked to fill the gap - like a text like would if there was no link.

Fixed on develop and picking to 2.3.x release branch

Quick note that this still occurs on mouseover, just not in normal state:

That is not the same issue. You can see above that the bullets were in the wrong place.
There is a separate PR that reduces the length of the underline, but that is not merged yet.
