📜 Description

When adding alt text to the image, the Mastodon Provider does not seem to include it when posted. Image still shows as "No Alt Text", which may hurt its spread in certain communities.

👟 Reproduction steps

1. Create Post
2. Attach Image
3. Click on Gear and add Alt Text
4. Post through the Mastodon Provider
5. Check Image for Alt Text

👎 Actual Behavior with Screenshots

Image shows no Alt Text when it was provided on Postiz.
