Include version name in released assets

[eriksven]

Is your feature request related to a problem? Please describe.
When downloading an asset from the release page in https://github.com/eclipse-leda/leda-distro/releases it can be later confusing to which release the file corresponded because for each release they are named the same (e.g., eclipse-leda-qemu-x86_64.tar.xz).

Describe the solution you'd like
It would be great to include the version name in the file names for future releases.

Describe alternatives you've considered
None
