Data like this https://github.com/ibexa/system-info/blob/032bc2f4fb92216b1c8a826bac37154cfb74e4c6/src/bundle/SystemInfo/Collector/IbexaSystemInfoCollector.php#L57
was not updated for v4 according to https://support.ibexa.co/Public/service-life
This means "end of maintenance" / "end of life" in the backend is empty, see screenshot.

There were plans to do this in a better way: https://github.com/ezsystems/ez-support-tools/pull/77
but that's not completed, so for now we should update the sysinfo file.

PR: https://github.com/ibexa/system-info/pull/37

Steps to reproduce:

1. Using v4.2 or v4.3, go to the backend
2. Go to system information

Expected: "End of maintenance" and "End of life" should show actual dates / months from our service life page.
Actual: These fields are empty, see screenshot.
