MuseScore inserts itself as the default app for .md files

Issue type

Other type of issue

Description with steps to reproduce

1. Install MuseScore
2. Try to open any .md file and it's now treated as a "MuseData file"

Expected behaviour

If I already have a default app for my .md files (which is widely used to mean Markdown) then MuseScore should not "steal" that file ending

On macOS, there is no such concept as "stealing" file types. MuseScore can only statically specify in its metadata that it can read .md files. The decision to immediately make it the default app for .md files is completely macOS's decision; MuseScore can't influence that.

What might help, is if we do not only list .md as an extension in CFBundleDocumentTypes, but also in UTImportedTypeDeclarations, to make very clear to macOS that MuseScore is not the "owner" of the md format, but probably this doesn't work because UTImportedTypeDeclarations doesn't have any influence on whether MuseScore appears in the "Open with…" list or not, according to https://stackoverflow.com/questions/21937978/what-are-utimportedtypedeclarations-and-utexportedtypedeclarations-used-for-on-i. (That page is about iOS, but it's the same on macOS).

(Incidentally, the MuseData file format is not related to Muse or MuseScore, see http://www.ccarh.org/publications/books/beyondmidi/online/musedata/; MuseScore only supports it as an import format.)

I'm not an app-developer so I won't argue with you since I have no idea how those things work. All I know is that I've installed both IDEs and text editors which all have some sort of "markdown support" and my default application for markdown editors has always stayed untouched.

Of course it might be the case that eg. Sublime and/or IntelliJ don't "register" that they can read .md files and just let's you open them anyway.

I just found it a bit weird to have my default application for a file type change without me doing anything so I thought I'd mention it here in the hopes that something could be done about it but if you have to register CFBundleDocumentTypes for stuff to work and then macOS does the changing then I guess there isn't really much to do :)
