Define standard URL convention for PowerShell function `.LINK` docs

[MariusStorhaug]

Problem

We need a documented, cross-org standard for the .LINK section in PowerShell comment-based help so Get-Help can reliably point users to published command documentation.

Today, MSXOrg/docs requires .LINK in help structure, but does not define a canonical URL shape for published function docs. That makes links inconsistent between repositories and harder to generate automatically.

Proposed standard

Document a canonical function-doc URL pattern, for example:

• https://psmodule.io/<ModuleName>/Functions/<FunctionName>/
• If function files are grouped by domain folder:
  • https://psmodule.io/<ModuleName>/Functions/<Group>/<FunctionName>/

Example:

• https://psmodule.io/Jwt/Functions/Token/New-Jwt/

Why this matters

• Consistent Get-Help navigation for all modules
• Easier automatic generation of .LINK blocks
• Less ambiguity for maintainers and tooling

Suggested docs updates

1. MSXOrg/docs: add URL-convention guidance under Coding-Standards/PowerShell/Functions.md (or Documentation.md).
2. PSModule/docs: add module-specific mapping guidance under Modules/Standards.md (or Process-PSModule docs) so framework tooling can generate links predictably.
3. Optionally define fallback behavior when grouped folders are not used.
