(MicrosoftDocsGH-11332) Fix pager info for built-in help function (MicrosoftDocs#11335)

Prior to this change, the documentation for the built-in
`help` function in `about_Built-in_Functions` incorrectly
stated that PowerShell always uses `more` for the pager
on Windows and the `PAGER` environment variable on
non-Windows systems.

This change:

- Clarifies that PowerShell uses a default pager for both
  Windows (`more`) and non-Windows (`less`) systems.
- Clarifies that when the `PAGER` environment variable is
  defined, PowerShell uses that command instead of the
  default pager on both Windows and non-Windows systems.
- Fixes AB#297346
- Resolves MicrosoftDocs#11332
