What is the current behavior?

Pin pydantic-settings to <2.2.0 due to issue highlighted in pydantic/pydantic-settings#245

Issue: #33

What is the new behavior?

• Added wrapper for 2.2.0 DotEnvSettings with new SettingsConfigDict parameter for dotenv_extra that defaults to ignore, reversing the behaviour introduced in 2.2.0
• Refactored FileConfigSettingsSource to use the new Json/Yaml/Toml handlers (including wrapper to instantiate at call time rather than initialisation time)
• Pinned pydantic-settings to be >=2.2.0, <2.3.0 given previous introduction of breaking changes in a minor version
