Update installation guide with Python compatibility

[tangelll]

I encountered an AttributeError related to AST objects in the untokenize dependency while installing DeepForest on macOS (M4) using Python 3.14.

Description

This PR adds a Python Version Compatibility matrix to the install.md documentation. The goal is to provide clear guidance for users on which Python versions are stable (3.10-3.12) and to warn about experimental versions (3.13+) where certain dependencies like docformatter currently fail due to AST changes in newer Python releases.

Related Issue(s)

No internal issue exists for this in DeepForest, but this change is needed to address installation failures on experimental Python environments. This is related to the known upstream issue: PyCQA/docformatter#327.

@tangelll Thank you for this input. We are working on getting to 3.14. We don't support 3.14 both in the release or dev versions requires-python = ">=3.10,<3.13".
