Expose options, parent, dependencies, and provider config (https://github.com/pulumi/pulumi-policy/pull/184).
Fix issue that prevented async policies from failing as expected when using validateResourceOfType or validateStackResourcesOfType (https://github.com/pulumi/pulumi-policy/pull/202).
Added a top-level optional enforcementLevel on PolicyPackArgs and made enforcementLevel on Policy optional. This allows setting the enforcement level at the Policy Pack level which will apply to all policies. Individual policies can set their own enforcementLevel to override the value specified for the Policy Pack. If no enforcement level is specified for either the Policy Pack or Policy, "advisory" is used. (https://github.com/pulumi/pulumi-policy/issues/192).
Add support for configuring policies. Policies can now declare their config schema by setting the config property, and access config values via args.getConfig<T>() (https://github.com/pulumi/pulumi-policy/pull/207).

Example:
```
{
    name: "certificate-expiration",
    description: "Checks whether a certificate has expired.",
    configSchema: {
        properties: {
            expiration: {
                type: "integer",
                default: 14,
            },
        },
    },
    validateResource: (args, reportViolation) => {
        const { expiration } = args.getConfig<{ expiration: number }>();

        // ...
    }),
}
```

Add support for writing policies in Python :tada: (https://github.com/pulumi/pulumi-policy/pull/212).

Example:

def s3_no_public_read(args: ResourceValidationArgs, report_violation: ReportViolation):
    if args.resource_type == "aws:s3/bucket:Bucket" and "acl" in args.props:
        acl = args.props["acl"]
        if acl == "public-read" or acl == "public-read-write":
            report_violation("You cannot set public-read or public-read-write on an S3 bucket.")

PolicyPack(
    name="aws-policy-pack",
    enforcement_level=EnforcementLevel.MANDATORY,
    policies=[
        ResourceValidationPolicy(
            name="s3-no-public-read",
            description="Prohibits setting the publicRead or publicReadWrite permission on AWS S3 buckets.",
            validate=s3_no_public_read,
        ),
    ],
)
