Add microdata from Schema.org to help SEO on events

[pataruco]

Description

When web spiders crawl sites they take on account semantic HTML to extract data to help search engines, but sometimes they need more info

To tackle this problem Google, Microsoft, Yahoo and Yandex founded Schema.org to provide consistent information (microdata) for spiders as HTML attributes

I added microdata to event components from Schema.org to help SEO on events

Can this PR be merged immediately after testing (eg. rebase, infrastructure update)?

Yes

Test setup (any additional steps that need to be taken to test the story)

Unfortunately, we cannot test this on local environment, because this need to be exposed to web spiders

At the moment when we google it red badger events we have the following response

This display should improve once this code is released

Do we need to add any documentation?

I used this schema

@pataruco this looks good. My only issue would be that we don't pass location, which looks like a required prop for the event schema (tested with https://search.google.com/structured-data/testing-tool/u/0/)
