Update release note link on photools.com

[thrinn]

Hi Mario,
this is really not important, but on https://www.photools.com/imatch-2020-whats-new/, the link to the release notes for IMatch 2020 still points to the notes for 2019.1.2. This might be irritating for new users, especially as there is an end-of-life announcement on the IMatch 2020 What's New page for version 2019.

Thanks. Missed that link
