Deprecate petablint with individual tables

[dweindl]

I think the main use case is running petablint on a full petab problem, so we don't need the option to pass individual tables. To support individual tables with the upcoming petab v2, we'd have to extend the list of files and require a version number. I don't it's worth maintaining this functionality (correct me if I am wrong), since validation of individual files is anyways rather limited.

Therefore, this adds deprecation warnings to command line arguments for individual PEtab tables and for the -y --yaml flags, which are no longer required, and the removal of which will make petablint easier to use.
