`Invoke-ScriptAnalyzer` parameterset ambiguity

Comece pelas declarações de parâmetros de Invoke-ScriptAnalyzer e inspecione os conjuntos de parâmetros Path e ScriptDefinition, incluindo seus metadados de vinculação posicional e de vinculação pela pipeline. A tarefa estará concluída quando ScriptDefinition não anunciar mais as vinculações posicionais ou pela pipeline por valor que são inalcançáveis, enquanto a vinculação pelo nome da propriedade continuar disponível; verifique o comportamento resultante do comando em relação aos exemplos na issue.

Summary

Both the -Path and -ScriptDefinition parameters of Invoke-ScriptAnalyzer are [string] parameters. Both accept ValueFromPipeline and both are declared as Position=0. While they exist in different parameter sets (each with two variants), there is no unique parameter in either set that would allow PowerShell to disambiguate and select the intended parameter set during binding.

As a result, the default parameter set (Path_SuppressedOnly) is always chosen. Any string passed down the pipeline (by value) or as a positional argument is bound to the Path parameter. This means that ScriptDefinition's Position=0 and pipeline (by value) binding declarations are effectively unreachable - any positional or pipeline string will always be bound to Path.

This isn't a bug, but is a design issue: the ScriptDefinition parameter advertises pipeline (by value) and positional binding, but there is no way for users to actually use these features due to parameter set ambiguity.

I propose removing ValueFromPipeline = true and Position = 0 from ScriptDefinition. This isn't a breaking change as they can't currently be used.

ValueFromPipelineByPropertyName is fine - the below works:

[PSCustomObject]@{ScriptDefinition = '$Var = 1'} | Invoke-ScriptAnalyzer
