DockerUrlUpdater not finding/adding specific versions

[moritzLanger]

Expected behavior

The DockerUrlUpdater should be able to find the versions of DockerDesktop with their download links. Ideally we can identify the stable download link for the latest version and determine (stable) SHA-256 checksums for the downloads so we do not need the manual latest version entry hacke (see also devonfw/ide#1293)

Actual behavior

No versions of DockerDesktop are found at all. It seems that the HTML structure has changed and the entire approach to crawl HTML websites with regex patterns will never be stable. However, DockerDesktop does not offer a well designed "API" for their downloads that we can use.

Steps to reproduce (bug) / Use Case of feature request (enhancement)

1. Watch the logs and the result of the github action update-urls or run the URL-Updater Process locally on your machine.

Related/Dependent Issues

Comments/Hints:

Suspected is that the Bug stemms from the else case in line 561 of the AbstractUrlUpdater is combined with the wrong if and should be moved one layer outside.

Affected version:

• ide-URLs

The issue seems to be caused by the DockerUrlUpdater.
Something must have been changed on their releases website again so that the regex we check does not match anymore.

For Docker-Desktop we should go away from HTML crawling.
I found this that looks promising:

• https://desktop.docker.com/win/main/amd64/appcast.xml
• https://desktop.docker.com/mac/main/amd64/appcast.xml
• https://desktop.docker.com/linux/main/amd64/appcast.xml
