Update Readme badges, Node support and examples

Refresh README: replace several badges (last-commit, stars, node, license), add a v7 alpha note recommending v6 for production, and update supported Node.js to >=18.0.0. Update supported dialect list (add Amazon Redshift and Snowflake’s Data Cloud, remove some older entries) and adjust documentation status notes. Remove the old installation section and replace the TypeScript/JavaScript examples with modern @sequelize/core usage (decorators-legacy, SqliteDialect, models array) and top-level await; remove the CommonJS example.
