Rule request: `Get-Content x | ConvertFrom-Json` should suggest adding `-raw` for `Get-content`

Summary of the new feature

When you call get-content file.json | convertfrom-json, funny things happen when file.json contains a comment at the top of the file.

Multiple places suggest that it's better to use get-content -raw for performance and predictability.

See:

• https://github.com/PowerShell/PowerShell/issues/12229
• https://stackoverflow.com/questions/71025659/set-property-value-on-object-loaded-from-json-containing-comments

Proposed technical implementation details (optional)

When get-content is piped to convertfrom-*, PSScriptAnalyzer should suggest adding -raw to get-content.

The same could apply to [xml] get-content file.xml.

What is the latest version of PSScriptAnalyzer at the point of writing

1.21

未指定源文件或测试。首先检查现有的 PSScriptAnalyzer 规则，了解将 Get-Content 通过管道传给 ConvertFrom-* 的情况，以及链接的 PowerShell issue；确定对 JSON 注释的预期处理方式和可能的 XML 情况。完成的标准是：分析器在适当情况下始终建议使用 -Raw，并且该行为有测试覆盖。
