.github: update issue template to collapse version details

The version information section is becoming very long, as some
of the commands that need to be run produce long output. Collapse
the version information under a details section so this can be
collapsed when investigating the issues.

Also comment out the initial instructions, since these are to help
the user when they are creating an issue, and does not need to be
included in the actual issue text.
