In this PR, I define the function returning meta tags with some defaults.

Thanks @Kazuhiro-Mimaki for taking on adding this utility 🤘

I realize you pretty much just copied my example, which is a fine start. That wasn't meant to be the final implementation. Would you be interested in making the following adjustments?

• Switch to v2 meta convention/don't use @remix-run/v1-meta at all, since eventually we would want to deprecate it
• Leverage this util on a route to showcase how it is to used. This will make it easier for further contributions.
• Add some unit tests to make sure the util is handling various use cases well

Thanks again for taking this on!

Thanks @brookslybrand for comments.

I implement.

• switch to v2 meta convention
• apply the util to app/routes/_marketing._index.tsx
• add unit tests

YES! This is exactly what I wanting, thank you @Kazuhiro-Mimaki 🙏

Probably some improvements we can keep making, like adding a default image, or logic on the twitter:card value of summary vs summary_large_image, but honestly that's all pretty small stuff to me. For the most part, I imagine we will want to just do the default image with summary_large_image anyway
