Bad permissions in docker-credential-pass release asset

[andyneff]

The permissions in the pass download are bad/insecure 667 instead of the standard 755, resulting in errors by default, or requiring people to chmod just to make it work out of the box.

-rw-rw-rwx 0/0         2818053 2021-06-07 09:16 docker-credential-pass

The secretservice has it correct in its tarball:

-rwxr-xr-x ebriney/ebriney 2495464 2021-06-07 09:22 docker-credential-secretservice
