fix: remove Arguments property deprecation analyzer (MP0010)

[thomhurst]

Summary

• Removes the MP0010 analyzer that warned when using the Arguments property on CommandLineToolOptions
• The Arguments property provides important flexibility for users to customize commands when the typed options class doesn't cover a specific CLI flag
• This escape hatch is valuable when new CLI features are added before the ModularPipelines model is updated

Test plan

• Verify the analyzers project builds successfully
• Verify no MP0010 warnings appear when using the Arguments property

Summary

This PR removes the ArgumentsPropertyDeprecatedAnalyzer (MP0010) analyzer that warned users about using the deprecated Arguments property on CommandLineToolOptions.

Critical Issues

Missing cleanup of auto-generated Resources.Designer.cs

The PR removes entries from Resources.resx (lines 192-199), but Resources.Designer.cs is an auto-generated file that still contains references to the removed resource strings:

• ArgumentsPropertyDeprecatedAnalyzerTitle (line 281)
• ArgumentsPropertyDeprecatedAnalyzerMessageFormat (line 290)
• ArgumentsPropertyDeprecatedAnalyzerDescription (line 299)

These auto-generated properties in Resources.Designer.cs are now orphaned since the source entries were removed from Resources.resx. The Resources.Designer.cs file needs to be regenerated to remove these entries.

Fix: Regenerate Resources.Designer.cs from the updated Resources.resx file, or ensure the build process does this automatically.

Suggestions

None - the removal is straightforward once the regeneration issue is addressed.

Verdict

⚠️ REQUEST CHANGES - The Resources.Designer.cs file needs to be regenerated to remove orphaned references to the deleted analyzer's resource strings.
