correct Julia minimum version to ≥ 1.6

[stevengj]

Your Project.toml currently lists julia = "1", but in my testing it seems that it requires Julia 1.6+ (and your CI tests also require 1.6+).

In particular, you depend on MicroMamba.jl, which also requires Julia 1.6+. But if you try to install PythonCall on an earlier Julia version, it just pulls in an earlier version of MicroMamba (before this commit).

On earlier versions of Julia, I get errors like:
