findlibs 0.1.0 doesn't support Python below 3.10

[fox91]

What happened?

From version 0.1.0 of findlibs it uses union type expressions (only allowed from Python 3.10) but the package classifiers allow install on Python versions below 3.10 (3.6, 3.7 and 3.8 are explicitly tagged).

What are the steps to reproduce the bug?

With Pythono 3.9 try to install and use findlibs, it will install 0.1.0 version that is incompatible.

Version
