[feature] Use same diff format in notification and in diff page.

[petersg83]

Describe the bug
Often I see that the diff in the notification is different than on the diff page. Sometimes there is a tiny change (like one red line and one green line) on the diff page but the notification diff is enormous (tens of lines of changed, into, added, removed).

Version
Exact version in the top right area: 0.46.02

Expected behavior
I expect the diff to be the same

Screenshots
Here is a small example where the lines "removed" are not the same in notification and in diff page

diff page

Hmm it's not a bug, more a "feature", because they use different ways to present the data

the coloured version is actually rendered by JavaScript which CANNOT be used in emails, discord, slack etc

[petersg83]

Yes I understand, so maybe the issue I have is more the "diff notification is complex whereas it seems it could be not"?
Here is an example of this morning.

Diff in changedetection.io:

As you can see, there are just some lines removed but the diff algorithm thought it was way more than that :P
What do you think?
