Fixed a small issue with the blog

After logging in with GitHub OAuth, I changed my GitHub username, but Mix-Space didn't sync it — because the name is already stored in the database after login. To update the name on the site, you need to modify the database.

Here's the process:

1. Connect to the server and run docker exec -it mongo mongosh mx-space
2. Run db.readers.find(). You can type show collections to list all collections.
3. Run:

db.readers.updateOne(
  { name: 'old name' },
  { $set: { name: 'new name' } }
);

4. Done
