Populate ALIASES documentation section based on actual command aliases

[MariusStorhaug]

Context

The Document-PSModule action generates documentation for PowerShell commands, including an ALIASES section. Currently, this section contains a placeholder template: This cmdlet has the following aliases, {{Insert list of aliases}}.

Request

The ALIASES section in generated documentation should be populated dynamically based on whether the command actually has aliases defined.

What is expected

• If the command has aliases, the section should list them:

  ## ALIASES
  
  This cmdlet has the following aliases:
  - New-CommandAlias
  - Some-OtherAlias

• If the command has no aliases, the section should state so:

  ## ALIASES
  
  There are no aliases for this command.

Acceptance criteria

• The ALIASES section is populated correctly based on actual alias data
• Commands with aliases show a bullet list of alias names
• Commands without aliases display "There are no aliases for this command."
• No placeholder template text remains in generated documentation

---

Technical decisions

To be determined during implementation planning — identify where alias data is available during documentation generation.

Implementation plan

• Identify where the ALIASES section is generated in Document-PSModule
• Query alias data for each command during documentation generation
• Render the alias list or "no aliases" message based on the query result
• Test with commands that have aliases and commands that do not
