Further refinement to #5290
Use pkg_remove_prefix()

Fixed #5290

Fix #5289 Available Packages version display

I left the "View changelog" code that was commented out, for future reference I guess when that data becomes available.
$index['version'] is still happily available in the $index array - so it just needs to be uncommented.

Fil;e conversion complete. Tested against multiple packages
