The /zone endpoint enforces IAM policies on authenticated requests, causing 403 for restricted keys (e.g. DBaaS-only) even though the endpoint returns public data. Skip credentials for list-zones so the call always succeeds.

# Description
`/zones` is public but the server enforces IAM on authenticated
requests, so a DBaaS-only key gets 403 for no reason.
`RequestTmpl` now has a `SkipAuth bool` field. When set, the generated
function skips `signRequest` and sends no `Authorization` header.
Operations opt in via `x-skip-auth: true` in the spec, so the guard
survives future regenerations.
**Snippet used to verify:**
```go
package main
import (
"context"
"fmt"
"os"
v3 "github.com/exoscale/egoscale/v3"
"github.com/exoscale/egoscale/v3/credentials"
)
func main() {
creds := credentials.NewStaticCredentials(os.Getenv("EXO_KEY"), os.Getenv("EXO_SECRET"))
client, _ := v3.NewClient(creds)
zones, err := client.ListZones(context.Background())
if err != nil {
fmt.Fprintln(os.Stderr, "error:", err)
os.Exit(1)
}
fmt.Printf("ok: %d zones\n", len(zones.Zones))
}
```
Or with the CLI (DBaaS-only profile, using any command that triggers a
zone switch):
```
# before fix
$ exo dbaas update --valkey-ip-filter 1.2.3.4/32 valkey-test-fix -z de-muc-1
error: unable to create client: switch client zone v3: get zone api endpoint: list zones: ListZones: http response: Forbidden: Forbidden by role policy for compute
# after fix
$ exo dbaas update --valkey-ip-filter 1.2.3.4/32 valkey-test-fix -z de-muc-1

**Go before** (master, DBaaS-only key):
```

```
**Go after** (this branch, same key):
```

The /zone endpoint enforces IAM policies on authenticated requests,
causing 403 for restricted keys (e.g. DBaaS-only) even though the
endpoint returns public data.
Add x-skip-auth to the list-zones operation in the spec. The
api.mustache template wraps the signing block in a
{{^vendorExtensions.x-skip-auth}} guard, so the generated
listZonesRequestBuilder omits the Authorization header.
The update workflow injects the extension after fetching the spec,
so the guard survives future automated spec updates. pom.xml now
reads the local api/openapi.yaml instead of fetching the spec at
build time, consistent with the workflow change.

_call_operation, when the operation islist-zones, the request is sent via a plainrequests.requestwithout credentials. No IAM check fires and all zones come back.Snippet used to verify:
