Draft: [ACI-4171] Delegate archive work to steps-xcode-archive

[Badlazzor]

TLDR; Parse config and enrich it to match requirements of steps-xcode-archive, but reduce step logic to minimal in this step.

• This step was using v1 version of most of our utils, including logging capabilities with 3rdparty tools (xcpretty).
• To support our own additional logs, we need to switch to v2 from the xcpretty, command and related utilities.
• The step structure was very outdated compared to our newer steps
• To introduce minimal user facing change we are keeping the inputs as-is but delegate the whole work to the code well tested in steps-xcode-archive
