Delete boilerplate first blog post

[graphieros]

The boilerplate first blog post is currently visible on the blog page, but should be deleted.
https://npmx.dev/blog/first-post

Hmm, I think it's intentional? It isn't listed in prod: https://npmx.dev/blog. It is listed in all other envs, e.g. https://main.npmx.dev/blog. It's accessible directly via URL on purpose.

Although at this point we should maybe just delete it, as it's served its purpose!
