[Feature Request] Dedicated intellisense for `.psd1`

[sharpchen]

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been requested.

Summary

Module metadata looks like certain shape of hashtable, can we have dedicated completion for its fields/keys?

Should also cover special psd1 file such as PSScriptAnalyzerSettings.psd1.

Proposed Design

No response

[TMA-2]

I can already say this would require PowerShell supporting schema validation for psd1 files (I'd like this too, honestly), which I don't see happening any time soon, and I'm very doubtful PSES would implement it when the psd1 format doesn't even have schema support yet.

However, you might want to follow this PR which is attempting to do something similar with PSScriptAnalyzer by adding JSON configuration support at least, for which I've written a basic schema.
