Updates an existing AI Gateway SNI.

## Request body

- UpdateAIGatewaySNIRequest: An SNI represents a many-to-one mapping of hostnames to a certificate. A certificate can have many hostnames associated with it; when the AI Gateway receives an SSL request, it uses the SNI field in the Client Hello to look up the certificate associated with the SNI.
  - `name` string, required: The name for this SNI. This value is immutable after creation.
  - `display_name` string, required: The display name for this SNI.
  - `hostname` union, required: A hostname used for TLS Server Name Indication (SNI) matching. Supports an optional wildcard segment at either end of the hostname (for example `*.example.com` or `example.*`).
    - string
    - string
  - `labels` PublicLabels: Public labels store information about an entity that can be used for filtering a list of objects. Public labels are intended to store **PUBLIC** metadata. Keys must be of length 1-63 characters, and cannot start with "kong", "konnect", "mesh", "kic", or "_".
  - `managed_by` ManagedBy: Stores information about what manages this entity, such as the tool or system responsible for its lifecycle (for example, `terraform`). Keys must be 1–63 characters long and start with an alphanumeric character.
  - `certificate` string, required: A reference to the certificate with which to associate the SNI hostname, by certificate name. The certificate must have a valid private key to be used by the SNI.
