LanguageRuleIgnoreMap rule suppressions for powershell is broken

[bzhu94]

Describe the bug
Using the --options-json to exclude rules for Powershell via something like this doesn't work: "LanguageRuleIgnoreMap": {"Powershell": ["DS104456","DS440001","DS440020"]}. I've tried using powershell, PowerShell, ps1, etc but the rules don't get suppressed when running DevSkim.

To Reproduce
Steps to reproduce the behavior:

1. Create a Powershell script that will flag a DevSkim rule.
2. Create a json file { "LanguageRuleIgnoreMap": {"powershell": ["DS-Rule-To-Suppress"] } }
3. Run DevSkim analyze with --options-json path-to-json-file
4. DevSkim analyze fails to suppress the DevSkim rule

Expected behavior
DevSkim analyze should suppress the DevSkim rule set in LanguageRuleIgnoreMap
