Replace old video of inventory.data.gov training

The skills development section https://resources.data.gov/categories/skills-development/

links to an old webinar on how to use inventory.data.gov https://www.youtube.com/watch?v=ciLYjDsF4lo

We should record a new video using the new metadata form, work with digitalgov team to get it uploaded to their YouTube channel, and then replace the link
