errors: fix incorrect argument label for array elements

[kimtaejin3]

This PR fixes array elements being incorrectly classified as "argument" in ERR_INVALID_ARG_TYPE and
ERR_INVALID_ARG_VALUE error messages.

for example:

Buffer.concat([1]);     

Before:
The "list[0]" argument must be an instance of Buffer or Uint8Array.

After:
The "list[0]" property must be an instance of Buffer or Uint8Array.

Updated related test expectations in:

• test-buffer-concat.js
• test-diff.js
• test-dns-setservers-type-check.js
• test-process-setgroups.js
• test-tls-set-default-ca-certificates-error.js
