Small CLI addition to allow running of cronjobs by job_code. This could be for debuging purposes or to add to your crontab.
To test generation of sitemaps
php bin/magento cron:run-job --job-code=sitemap_generate
The job-code is that same as would be found in the cron_schedule table
Or in a modules crontab.xml for example:
https://github.com/magento/magento2/blob/2.4-develop/app/code/Magento/Sitemap/etc/crontab.xml#L10
