Require numpy 2.1 or newer in tests. Adopt SPEC-0 in the package. (#321)

* Switch `reshape` to `shape` and drop support for old numpy versions.

* Fix tox.ini missing env from envlist.

* Remove pre-commit.ci badge since we're not using it anymore.

* Was actually added in numpy 2.1. So we also don't support numpy 2.0.

* Aaaand, we can remove a deprecation warning suppression.

* Full SPEC-0

 A plugin to create Matplotlib plots from napari layers
 
-----------------------------------
+---
 
 ## Introduction
+
 `napari-matplotlib` is a bridge between `napari` and `matplotlib`, making it easy to create publication quality `Matplotlib` plots based on the data loaded in `napari` layers.
