docs(github): issue templates ask for the platform

bug_report.yml and feature_request.yml get a required platform dropdown (Windows,
Linux (KDE Plasma), macOS) first in the form; the bug report's Windows-only
wording (ghost tiles, systeminfo, whkdrc, komorebic check) is scoped to Windows or
made platform-neutral; the feature request text names all three platforms.
config.yml links the Windows docs site plus the Linux and macOS index pages on
master (repo-relative GitHub links). Existing fields and labels are kept.

Verified: yq parses the three files. Links not fetched (the docs/linux and
docs/macos index files exist in the tree; they resolve on GitHub once pushed).

         You can run `komorebic visible-windows` when the ghost tile is present on your workspace to retrieve the invisible window's exe, class name and title, and then use that information to [ignore the window](https://lgug2z.github.io/komorebi/common-workflows/ignore-windows.html) responsible for the ghost tile.
