🎉🎉🎉 Mastodon v4 support

[OlshaMB]

Describe

Mastodon v4 just dropped with many new features such as:

• [x] toot editing
• [ ] ability to follow hashtags
• [ ] posts translation

Why

• compatibility with mastodon v4 ability to edit toots:
• fix mistakes in toots ability to follow hashtags: it's already in client partially, but i am talking about ability follow hashtags in main feed.
• will help follow topics/hashtags that user interested in. posts translation:
• help understand toot in the foreign language It's kind of bad in the mastodon, because of libretranslate's bad trasnlation(so i would think twice about wich translator to use)
