[FE] Content-Panel: Publish Blog Posts

[edichoska]

When a blog post is created it has a status: draft. We want when the content-manager is finished writing a blog post, to be able to change the status to "In Review".
Only admins would be able to publish blog posts.
So if the user has a role: content-manager, he should only be able to change the status to "In Review".
When creating and editing a blog post, we should add an option to change the status of the blog post: https://api.learnhub.mk/docs/#content-PATCHcontent-blog-posts--id--statuses
