feat: remove snapshot processor and flat/snapshot config

 the `all` configuration may change in any release and is thus unsuited for
 installations requiring long-term consistency.
 
-## Snapshot processing
-
-> [!NOTE]
->
-> This is only relevant for `eslint.config.js`
-
-This plugin provides a
-[custom processor](https://eslint.org/docs/latest/extend/custom-processors) to
-allow rules to "lint" snapshot files.
-
-For `.eslintrc` based configs, this is automatically enabled out of the box but
-must be opted into for `eslint.config.js` using the `flat/snapshots` config:
-
-```js
-const jest = require('eslint-plugin-jest');
-
-module.exports = [
-  {
-    ...jest.configs['flat/snapshots'],
-    rules: {
-      'jest/no-large-snapshots': ['error', { maxSize: 1 }],
-    },
-  },
-];
-```
-
-Unlike other configs, this includes a `files` array that matches `.snap` files
-meaning you can use it directly
-
