Update dependencies & other general maintenance

* Upgrade XO
* Update TypeScript-related dependencies — Don't upgrade @sindresorhus/tsconfig to v6 since it requires TS 5.5 and we test with 5.2.
* Update dev dependencies
* Update dependencies
* Rebuild lockfile
* Upgrade CodeCov action
* Update reporter log instructions and remove deprecation warnings
* Make Node.js 22.6 the recommended development version
* Remove Node.js 21 from the engines list: It's no longer maintained by Node.js itself, see also <https://github.com/avajs/ava/blob/main/docs/support-statement.md>.

+We will drop support for odd-numbered Node.js versions (e.g. `21` or `23`) *without* bumping AVA's major version number.
 
 We try to avoid *accidentally* dropping support for non-latest Node.js releases. If such breakage does occur we'll accept pull requests to restore functionality. We might decide to deprecate the offending AVA release and bump AVA's major version number instead.
