Does not work with ckeditor 5

Problem/Motivation

When using ckeditor5 the new lines in the value of the textfield are removed and just one long string of html is returned

For example: <p>line on</p><p>https://some-oembed-url</p><p>line three</p>
all as one line of text.

This causes the regex in this module to fail and the urls are not picked up.

Steps to reproduce

• Use ckeditor5 with soembed on the input filter
• Add a url that should have an oembed on a new line, and save the node
• the url is not embedded.

Proposed resolution

update the regex to account for this.

I will provide a patch
