preferences file does not support $env: variables

Reproduza o problema com PSScriptAnalyzerSettings.psd1 e Invoke-ScriptAnalyzer usando tanto um CustomRulePath simples quanto uma expressão $env: ou $PSScriptRoot. Rastreie como o arquivo de configurações é analisado e como CustomRulePath é resolvido; considera-se concluído quando valores de variáveis de ambiente compatíveis são aceitos sem o erro de validação da tabela hash e o comando documentado funciona.

Expected behavior

# # PSScriptAnalyzerSettings.psd1
# @{
#    CustomRulePath = "rules.psm1"
# }
Invoke-ScriptAnalyzer -Path .\test.ps1 -Settings ./PSScriptAnalyzerSettings.psd1

outputs: (correct)

RuleName                            Severity     ScriptName Line  Message
--------                            --------     ---------- ----  -------
PSAvoidInvokeSomething              Warning      test.ps1   1     The command 'Invoke-Something' should not be used. Please
                                                                  use 'Invoke-SomethingElse' instead

Actual behavior

# # PSScriptAnalyzerSettings.psd1
# @{
#    CustomRulePath = "$PSScriptRoot/rules.psm1"
# }
Invoke-ScriptAnalyzer -Path .\test.ps1 -Settings ./PSScriptAnalyzerSettings.psd1

Outputs:

Invoke-ScriptAnalyzer: Value in the settings hashtable should be a string or an array of strings: line 2 column 22 in file [...]\Powershell\PSScriptAnalyzerSettings.psd1

Reasoning

according to this article,

Module manifests are loaded in RestrictedLanguage mode and may use these additional variables:
$PSScriptRoot
$PSEdition
$EnabledExperimentalFeatures
Any environment variable, like $env:TEMP

relative file paths CustomRulePath for my environment
were resolving relative to the cwd instead of relative to the settings.file in neovim. the
./rules.psm1 and rules.psm1 were not resolving correctly.

~/.../Powershell/PSScriptAnalyzerSettings.psd1
where '~' expands to HOMEDIR does work
