Fix HashManager make() error

Error encountered:
Call to undefined function HyperfExt\Hashing\make()[92]

File affected:
vendor/hyperf-ext/hashing/src/HashManager.php

Cause:
The helper make() was not imported:
use function Hyperf\Support\make;

Solution:
Added the proper import so HashManager can call make() without errors.

---

Minor refinement in hashing.php

Changes:

• Added import for env helper:

  use function Hyperf\Support\env;

• Added type int type:
  rounds' => (int) env('BCRYPT_ROUNDS', 12)
