handle deb/rpm packaging split (1 to 3) for redpanda 24.2

[jackietung-redpanda]

Upcoming Redpanda release 24.2 includes a split of the monolithic redpanda package into three separate packages:

• redpanda-rpk
• redpanda-tuner
• redpanda

All three must now be downloaded and installed, instead of the single one pre 24.2. Order must be as specified above (top to bottom). This applies to both rpm AND deb.

I see #105 was merged, which takes care of airgapped installations. I think we need something similar for regular installs for releases after 24.2, similar to what's done here https://github.com/redpanda-data/vtools/commit/3c37ce3fa760b114def803edb79238b7813f4855.
