• [Feature] Add "alias" for "pwsh", short for "powershell" mProjectsCode/obsidian-shiki-plugin#68

Additional context

pwsh is the name of the executable ever since Dotnet Core (cross platform) was created, and PowerShell Core (cross platform) was made on top of it. Before that we had Windows PowerShell, with executable name powershell.

• Old Windows PowerShell: powershell
• New PowerShell: pwsh

Other code highlighters supports pwsh as alias for powershell.
