Improvement: hide environment variables in altool output

[priitlatt]

Action app-store-connect publish uses xcrun altool to perform the package upload to App Store Connect. With some Xcode versions altool logs out all environment variables and their values as a Ruby hashmap in case of an error.
Usually this is not a desired behaviour, especially in a CI envioronment. This is because environment variables can contain various secrets such as private keys, passwords etc, and they would leak to build logs that way.

In order to tackle this, replace environment variable values in altool output with ellipsis. That is

ENV: {"VARIABLE_1" => "value", "KEY" => "other value"}

becomes

ENV: {"VARIABLE_1" => "...", "KEY" => "..."}

in the output.

Note that in the verbose logs full unmodified altool output is available for inspection.
