Equivalent usage of Simpleclient in micrometer-registry-prometheus `1.13.x`

从 1.13 Migration Guide 以及 issue 中提到的 PrometheusMeterRegistry、Collector、MetricFamilySamples 和 TextFormat API 开始。跟踪当前 client_java 版本中的对应 API，并为全部三个场景记录迁移等价方案，包括任何必需的代码更改。当迁移指南清楚地解释这些替换项时，即视为完成。

Hi Team! We are migrating our project from micrometer-registry-prometheus:1.12.8 to version 1.13.8 . I see that the io.prometheus:simpleclient:jar:0.16.0 has been deprecated.

We have few scenarios which I do not see in the migration guide.

Here are few scenarios,

1. What is the equivalent of io.prometheus.client.Collector.MetricFamilySamples and the MetricFamilySamples.Sample

   PrometheusMeterRegistry instance = new PrometheusMeterRegistry(PrometheusConfig.DEFAULT);
   MetricFamilySamples samples =  instance.getPrometheusRegistry().metricFamilySamples()

 if (sample == null || sample.name == null || sample.labelNames == null || sample.labelValues == null) {
      LOGGER.error("The provided Sample object is either null or one of its fields is null: {}", sample);
      throw new IllegalArgumentException("The provided Sample object is either null or one of its fields is null: " + sample);
    }

2. Is the import io.prometheus.metrics.model.registry.Collector a replacement of io.prometheus.client.Collector, however, I couldn't find the below in the new Collector.

Enumeration<Collector.MetricFamilySamples> metricFamilySamples;

3. Similarly how we can replace the io.prometheus.client.exporter.common.TextFormat?

Could you please help me with the code changes. Also, can you share any additional docs available that we can follow for migrating from the usage of simpleclient.
