hubspot.utils.signature is broken for python < 3.11

hubspot/utils/signature.py

---

• datetime.UTC (alias for datetime.timezone.utc) is available since python 3.11, see What’s New In Python 3.11. For older versions, this will raise an ImportError.
• Changed in commit f31fa724a3fa28a322c45681d318b8a1030f943d.
• Related to #263.

Possible solution: Use timezone.utc.
