"An update for MuseSounds is available" dialog appears on launch with no clear way to resolve

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

On launching MuseScore, a dialog box now appears about an update to MuseSounds:

An update for MuseSounds is available

To keep MuseSounds running smoothly, MuseScore Studio needs to close briefly so MuseHub can apply the update. You'll be prompted to relaunch MuseScore Studio when it's ready.

Despite the message, clicking the "Quit & launch MuseHub" button does not seem to apply any sort of update, it merely opens the MuseHub website. Relaunching MuseScore just shows the same message again; no update seems to have been applied. Dismissing it with "Not now" allows me to use the application as normal.

Issues:

1. The link just takes you to the MuseHub webpage (https://www.musehub.com/). It's not clear what you need to do from here

• If it's possible to install the MuseSounds update manually, it's not clear how or which package should be downloaded. There are many options, most of which cost money.
• If the MuseHub desktop application is required, there should be clearer instructions on this. MuseScore should detect this and send you directly to the download page.

2. If the user does not want to install this update, there should be an option to ignore it, instead of being nagged every time on startup.
