fix: set minimal version number needed for plac

[maarten-k]

The plac @flg decorator is only supported from place version 1.2.0. In some entangled environments, an old version of place is installed (for example: snakemake/snakemake#2276)

Update plac version to be at least 1.40, since plac<1.39 does not support python 3.12.
