- Bug in ansible playbook

Details:
If the machine has a directory /usr/lib/jvm/jdk-17.* but no corresponding symlink from `/usr/lib/jvm/jdk-17` then the adoptopenjdk-install role will go into the "Does not exist - install it" mode and install the latest version, and if that's not the same as the one that was on the machine it will get confused by the presence of two candidate directories for the symlink target, and therefore not create one and abort the playbook.

Locate the adoptopenjdk-install role and inspect the checks for /usr/lib/jvm/jdk-17.* directories and the /usr/lib/jvm/jdk-17 symlink. Reproduce the case with an existing versioned directory but no symlink, then verify that the playbook selects the existing installation and completes without conflicting candidates.
