fix: Added support for multiple name patterns to Permissions

@@ -36,7 +36,7 @@ The permission model is based on the following components:
 The `Permission` class identifies a single permission configured on the feature store and is identified by these attributes:
 - `name`: The permission name.
 - `types`: The list of protected resource  types. Defaults to all managed types, e.g. the `ALL_RESOURCE_TYPES` alias. All sub-classes are included in the resource match.
-- `name_pattern`: A regex to match the resource name. Defaults to `None`, meaning that no name filtering is applied
+- `name_patterns`: A list of regex patterns to match resource names. If any regex matches, the `Permission` policy is applied. Defaults to `[]`, meaning no name filtering is applied.
 - `required_tags`: Dictionary of key-value pairs that must match the resource tags. Defaults to `None`, meaning that no tags filtering is applied.
 - `actions`: The actions authorized by this permission. Defaults to `ALL_VALUES`, an alias defined in the `action` module.
 - `policy`: The policy to be applied to validate a client request.
