steamcmd app_info_print issue prevents update/install

[DrPsychick]

Hi there 👋,

there are a few other issues possibly related to this: #1276, #1245

the cause seems to be an issue with steamcmd which is not reliably reporting app information: ValveSoftware/steam-for-linux#9683

how to detect the issue

arkmanager does not print a version on the console:

Your server is already up to date! The most recent version is .

or

Querying Steam database for latest version...
Current version:
Available version:
Your server is up to date!

how to workaround the issue

run arkmanager install or arkmanager update --force manually which bypasses the check if an installation or update is needed.

Found by a user of my drpsychick/arkserver docker container, resulting in this workaround: SickHub/arkserver#20

It appears that the actual issue is that app_info_print no longer waits for a request if it has to send one to get the app info.

7f95727 should work around this by waiting for the appcache.vdf to be created before requesting then printing the app info.
