Data/UUID: Upgrade composer dependency for PHP 8.1 (ILIAS 9 only)

[mjansenDatabay]

This PR upgrades the UUID composer dependency used in ILIAS (ramsey/uuid). This does not work for PHP 7.4 (see: failed build) and MUST only be merged for ILIAS 9. The latest version of ramsey/uuid fixes some PHP 8.1 issues so I suggest to upgrade it.

Hi Jour-Fixe,

I have assigned the JF-label because we should discuss how we want to deal with dependencies that where introduced by people who are not active in the community anymore.

Best regards!

Jour Fixe, 16 MAY 2022 : We would like to handle external libraries like core components where a maintainer is taking care of the code. In this case, @chfsx (who uses it) will have a look at the library and notify us in case something is changing in this lib.
