Update ps1 completion

[deflektor]

Hi all,

Made an update to the default completion for ps1

1. Removed shortcut entries
   Code completion, in powershell, should be more descriptive.
2. Added completions with individual values for
   ** Language
   ** Theme
   ** Other argument with options

Works with Powershell Core 7

Pull Request Overview

This PR updates the PowerShell completion script for bat to provide more descriptive and comprehensive tab completion functionality. The update removes shortcut entries and adds dynamic completions with individual values for languages, themes, and other command arguments.

• Replaced template placeholders with hardcoded "bat" command name
• Added dynamic completion functions for themes and languages with descriptive output
• Enhanced argument-specific completions with predefined value arrays for various options

Comments suppressed due to low confidence (1)

• The variable name '$themes' is misleading since this function processes languages, not themes. It should be named '$languages' for clarity.

        $themes = bat --list-languages | ForEach-Object{[pscustomobject]@{MyParameter=$_.Substring(0,$_.IndexOf(":")).Trim();MyDescription=$_.Substring($_.IndexOf(":")+1)}} | select-object

The condition logic appears incorrect. The original condition checked if the element starts with '-' OR equals $wordToComplete, but now it only checks equality. This could break command parsing logic.

Suggested change

	$element.Value -eq $wordToComplete) {
	#-or $element.Value.StartsWith('-')
	$element.Value -eq $wordToComplete -or $element.Value.StartsWith('-')) {

It seems like Copilot missed that it was commented out previously?

changing back, would not complete the optional entries, I receive only the default part.
