Specify aria label with video shortcode

I have:

• searched the issue tracker for similar issues

Bug description

I am using the video shortcode like this:

{{< video file-name.mp4 >}}

I would like to be able to specify an aria label. I understand that right now this gets hard-coded as "Video Player", but I would like to be able to customize this based on the video content for accessibility, maybe something like this:

{{< video file-name.mp4
    aria-label="Video demonstration of Positron's multi-language coding and data exploration features"
>}}
