[BUG] 10.4 and later: $npm_package_config_* variables no longer work for arrays about cli

[milaninfy]

@Twipped It can be accessed as "echo $npm_package_config_foo_0 $npm_package_config_foo_1 $npm_package_config_foo_2 $npm_package_config_bar"
This was done here npm/run-script#194

[Twipped]

I understand that, but the behavior where the array was coerced into arguments has vanished, and it broke some of our workflows.

@Twipped This is not a bug and it's expected behaviour and those values can be accessed as _0, _1, _2 and so on based on how many values are there in array. This behaviour got changed in v7 and it got fixed in this PR npm/run-script#194
