Need a method to get the channel ID using the current channel name

We need a way to get the channel ID when provided the current channel name as an input. Previously this could be done using the channels.info API method, but now with that method fully deprecated and disabled, we don't have any other reliable method of doing this. We could theoretically post a new message to the channel using chat.postMessage, which returns the channel ID, then remove that message, but this seems like overkill.

The use case is that a user provides a channel name as input, and we want to convert that channel name to an ID and store that ID for later use when posting messages. Obviously the name may change over time, so using the channel ID is ideal.

从 slack_sdk.web.WebClient 的同步和异步入口开始，检查现有的频道相关方法。将所请求的按频道名称查找与已弃用的 channels.info 以及 chat.postMessage 这一变通方案进行比较；完成的标准是提供一种可靠的方式来获取并存储频道 ID，而无需发布临时消息。
