[chore][receiver/splunkenterprise] Splunkent wire component (#32795)

**Description:** Graduate splunkenterprise receiver component to alpha

**Link to tracking Issue:**

**Testing:** Performed `make otelcontribcol` and ran resulting binary
with the following config:
```yaml
extensions:
    basicauth/indexer:
        client_auth:
            username: admin
            password: securityFirst
    basicauth/cluster_master:
        client_auth:
            username: admin
            password: securityFirst

receivers:
    splunkenterprise:
        indexer:
            auth:
              authenticator: basicauth/indexer
            endpoint: "https://localhost:8089/"
            timeout: 45s
        cluster_master:
            auth:
              authenticator: basicauth/cluster_master
            endpoint: "https://localhost:8089/"
            timeout: 45s

exporters:
  otlp:
    endpoint: 127.0.0.1:8000

service:
  extensions: [basicauth/indexer, basicauth/cluster_master]
  pipelines:
    metrics:
      receivers: [splunkenterprise]
      exporters: [otlp]
```

and received the following output:
```

```

indicating that the collector was able to successfully start with the
component configured.

**Documentation:** Documentation was updated to indicate change in
status from development to alpha
