feature request: markdown field support in aliases

Currently, when writing an alias such as:

---@alias fontmeta.alias.NameTableFormat
---| 0 # Always 0 for TrueType, OpenType accept it as well. See [OpenType Name Table Version 0](https://learn.microsoft.com/en-us/typography/opentype/spec/name#naming-table-version-0).
---| 1 # Can only be 1 for OpenType. See [OpenType Name Table Version 1](https://learn.microsoft.com/en-us/typography/opentype/spec/name#naming-table-version-1).
---| integer

The markdown of the description text (after the #) are not parsed as markdown:

Would be neat if the alias was parsed as multiple tags, similar to how it is done with arguments:
(the data argument)

该 issue 未指定文件或测试。首先跟踪 alias 解析，并将其与报告中描述的现有参数/数据 Markdown 处理进行比较；当 alias 描述中的 Markdown 能够与参数描述保持一致地渲染时，即视为完成。
