Short videos + guide collating them

[lcolladotor]

We want to create a collection of short videos (likely shared on YouTube) demonstrating how to use the different features of the recount3. We will collate these videos into a new user guide (a new vignette). We will aim to clarify common questions from users in these videos.

Some of these videos will be inspired by actual use cases we hear from our users that they have asked either here on GitHub or the Bioconductor Support website https://support.bioconductor.org/tag/recount3/.

This will be an evolving process as new videos will have to be made to reflect new features added to recount3.
