v1.2.0 - Deprecation of Python 3.7

Since Python 3.7 has entered end-of-life and many dependencies (including mypy) are no longer supporting it, pydantic-yaml won't support it either. The latest version to support Python 3.7 is 1.1.3.

What's Changed

• Bump ruff from 0.0.289 to 0.0.291 by @dependabot in #108
• Bump mypy from 1.4.1 to 1.5.1 by @dependabot in #93
• Remove Python 3.7 support, targeting 3.8 - 3.11 by @NowanIlfideme in #109
