Add examples for how to upload videos for retried tests

[jennifer-shehane]

I’ve had people open this issue a few times now, asking for a feature to also upload videos for retried tests:

• Upload videos of flaky tests (tests with retries) cypress#16377
• Enable Video only on Retry cypress#16672
• Record videos after first test failure - to capture video only during retries cypress#16681

This is actually already possible, but I don’t think people are finding it since it’s in the ‘after:spec’ API page. Why would anyone look there?

• This adds the example to the ‘Screenshots & Videos’ page as well as ‘Test Retries’.
• It also frames the example as ‘upload video on test retries’ instead of ‘delete videos that didn’t pass’, which is less direct on the intent.
• Question: Is there a way to reuse snippets of the docs? We have this same exact code sample in the docs in 3 places now and I would prefer if it could be edited in one place.

@jennifer-shehane I am looking into how to create a re-usable markdown component. I think we can leverage this: https://www.npmjs.com/package/@nuxtjs/markdownit

I will submit a PR if I get it things working and keep you posted.

I wasn't able to get that @nuxtjs/markdownit library working. I will see if I can find another way.

@jennifer-shehane I have created DX-324 issue to try and come up with a solution to reuse code blocks in our docs. The DX team is now aware and this is in our backlog now.

@robertguss Very cool. We used to have this with the old hexo framework, although it was very flawed. So I know there are a few places it could be used.
