[bp-2.15] Fixes permission for cache json file to 644 (#83016)

Until ansible-core 2.12 the facts cache file created by this module, have permission set as 644 which allows the other users to read the cache, since ansible-core 2.13, we create the temporary file, but we do not set the permission after renaming the temporary file.  Adding the line to set the permission to allow other users/groups to read this file.
