fix: minimal Linux installation filetype

[brandonskiser]

Description of changes:

• Update the file type of update packages for Linux minimal installations to tarZst instead of tarGz. The release for v1.4.6 (included in v1.5.0) has broken update logic for Linux minimal installs where the app will always download a tarGz and attempt to unpack using zstd. This change will revert back to the previous behavior of always using tarZst.
• Add some extra debug statements when updating.
