feat: curated blocklist go-auth0 v1 support

[KartikJha]

Add Auth0-managed curated blocklist support to Network ACLs

🔧 Changes

Adds support for Auth0-managed curated blocklist categories on Network ACL rules.

• Add the Auth0Managed *[]string field to the NetworkACLRuleMatch struct (JSON key auth0_managed), allowing rules to match against Auth0-curated blocklist categories such as auth0.icloud_relay_proxy.
• Regenerate the corresponding GetAuth0Managed() []string accessor in management.gen.go.

Usage:

acl := &management.NetworkACL{
    Description: auth0.String("block icloud relay proxy"),
    Active:      auth0.Bool(true),
    Priority:    auth0.Int(1),
    Rule: &management.NetworkACLRule{
        Action: &management.NetworkACLRuleAction{Block: auth0.Bool(true)},
        Match: &management.NetworkACLRuleMatch{
            Auth0Managed: &[]string{"auth0.icloud_relay_proxy"},
        },
        Scope: auth0.String("authentication"),
    },
}
err := api.NetworkACL.Create(context.Background(), acl)

🔬 Testing

• Added TestNetworkACLManager_CreateWithAuth0Managed, which creates a Network ACL with an Auth0Managed match, reads it back, and asserts the field round-trips correctly. Backed by an HTTP recording (TestNetworkACLManager_CreateWithAuth0Managed.yaml).
• Added the generated accessor test TestNetworkACLRuleMatch_GetAuth0Managed covering the non-nil, empty, and nil-receiver cases.
