Release v2.4.2: replace em-dashes with ASCII hyphens to fix encoding parse errors

UTF-8 em-dashes (U+2014) in Elysium.Common.ps1 string literals were
being misinterpreted by Windows PowerShell as containing quote
characters when the file was read without a UTF-8 BOM. This caused
cascading parse errors: unexpected tokens, missing closing braces,
and missing catch blocks.

All em-dashes in .ps1 files have been replaced with ASCII hyphens.
All versions bumped to unified v2.4.2.
