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:

• ConvertFrom-Json includes $null element on output if input starts with blank line PowerShell#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
