Add word limit

[XJXuan888]

Add a limit to the number of characters in the user input box for the composer and sheet name in the upload page

Description

Currently, there is no character limit when uploading a sheet and entering the sheet name and composer name. Upon uploading, it obscures the sheet thumbnail as well as the display image of the sheet as the characters just populate the screen.

Fixes # (issue)

Now, an error message is displayed when it hits the character limit and disables users from clicking the next button.

Hey @XJXuan888, thanks for the PR. Could you maybe upload a demo video? It makes it easier to review. If not it's also fine tell me then
