CI: Fix pico, add combined uf2 & artifacts

CI for release was using outdated way of building atomvmlib-pico.uf2/atomvmlib-pico2.uf2, fixed to the ninja building.

Moved said building to a job before, the various pico builds.

Removed wrong 'mv atomvmlib.uf2' segment, file is non-existent on new ninja builds.

Added combined uf2 artifacts using uf2tool.

Upload the artifacts, so they are available for testing.

Include combined artifact in release.
