Context

Cordova-android 10 made bundle package type the default : apache/cordova-android#1268
So using this step's option android_app_type: apk with cordova-android@10 still builds an aab (and make the step failed because apk result is not found)

Changes

Always specifying ---packageType has no downsides and make it compatible with all cordova-android versions.

Hey @QuentinFarizon, thank you for the contribution. We agree with the changes, it's a good idea to always specify the package type.

I wanted to make two small changes to this PR (since you checked the "allow changes from owners" checkbox), but my changes landed on a different branch and the commit is not part of this PR. I assume this happened because you opened this PR from your master and not from a separate branch.

Anyway, here are the changes that I wanted to make before merging this PR. One is a Golang style fix, the other is fixing the tests: 9899f21

I pushed with you changes integrated.
Sorry for the style, I'm not a go developer ;)

No worries and thank you for the contribution :) I merged the PR, the new step version will be available soon.
