Change sitemap.settings.plugins.*.weight from type integer to weight

Problem/Motivation

At time-of-writing, sitemap supports Drupal core 10.2 and higher.

When we drop support for 10.2, we can change sitemap.settings.plugins.*.weight from type integer to weight. The proposed guideline for semantic versioning for contributed projects in relation to Drupal core compatibility 🌱 Guidelines for semantic versioning and Drupal core support Active currently suggests dropping support in a minor release. (see also #3465600-4: Drop support for Drupal 9.x, 10.0 and 10.1 → ).

(note this issue is split from 📌 Improve configuration schema and how we use it Active )

Proposed resolution

Change sitemap.settings.plugins.*.weight from type integer to weight in config/schema/sitemap.schema.yml

1. Wait until we drop support for Drupal core 10.2
