Allow toolz 1.0.0

[MaximGovorchuk]

Issue #, if available:

Description of changes:
Allow toolz 1.0.0 version as a dependency.

According to the toolz's release notes it's safe to do since the changes between 0.12.1 (the last 0.x version) and 1.0.0 are strictly about dropping Python 3.7 support, adding Python 3.13 test and some docs updates:
pytoolz/toolz@0.12.1...1.0.0

Note that there are 2 errors in the test result. I believe it's because I'm on Mac and there is no mxnet wheel available for it.

Note that this change is similar to #3301 with the difference of having a lesser scope, i.e. by allowing 1.0.0 version only
