[Repost] PSUseProcessBlockForPipelineCommand does not recognize use of $input within an End block

Repost: Hoping to get some clarification, since this was mechanically closed based on a factually incorrect response to #1912 .

Steps to reproduce

Invoke-ScriptAnalyzer -IncludeRule PSUseProcessBlockForPipelineCommand `
	-ScriptDefinition 'Param([Parameter(ValueFromPipeline=$true)][psobject] $Item); End {$input |ConvertTo-Json}'

Expected behavior

(no output)

Actual behavior

首先，使用提供的指令碼定義和 PSUseProcessBlockForPipelineCommand 規則，透過 Invoke-ScriptAnalyzer 重現此問題。追蹤規則如何處理在 End block 中透過 $input 參照的管線輸入；完成的標準是該範例不產生任何診斷，同時保留規則在確實缺少 process blocks 時的行為。
