Support new download links on Mac

[barmac]

Is your feature request related to a problem? Please describe.

Due to camunda/camunda-modeler#4238, the download links for MacOS will change to support both arm64 and x64 architectures.

Describe the solution you'd like

The tool should detect the architecture via arch and adjust the links accordingly, but only for the nightly and the upcoming releases.

• Use old file name for 5.22.0 and earlier version
• Use arch-adjusted file name for any release after 5.22.0
• Use arch-adjusted file name for the nightly

Describe alternatives you've considered

None.
