Issue

Poetry fails to version solve when adding both seaborn and matplotlib.

I ran poetry init in my project directory, switched to the venv using poetry shell and there added poetry add seaborn and then poetry add matplotlib:

$ poetry add seaborn
Using version ^0.12.1 for seaborn

Because no versions of matplotlib match >3.6.1,<4.0.0
 and seaborn (0.12.1) depends on matplotlib (>=3.1,<3.6.1 || >3.6.1), seaborn (0.12.1) requires matplotlib (>=3.1,<3.6.1 || >=4.0.0).
And because no versions of seaborn match >0.12.1,<0.13.0, seaborn (>=0.12.1,<0.13.0) requires matplotlib (>=3.1,<3.6.1 || >=4.0.0).
So, because git-denoiser depends on both seaborn (^0.12.1) and matplotlib (^3.6.1), version solving failed.

Even though seaborn already installs matplotlib 3.6.0, poetry doesn't detect it's there. Instead it tries installing a version that's incompatible with seaborn, i.e. ^3.6.1.

Reversing the steps also doesn't work.
