docs: rename Hosting card, fix Edit/Raise issue links, add docs issue template

- "How to Host" card on the docs landing page is now labeled
  "Deployment".
- Right-rail "Raise an issue" link previously pointed at the
  archived `reflex-dev/reflex-web` repo and used `&` in the URL,
  which sent the literal `amp;body=...` to GitHub. Repoint at
  `reflex-dev/reflex`, fix the entity, prefill title/body with the
  current page path, pre-select the new "Documentation" issue
  template tab, and pre-add the `documentation` label.
- "Edit this page" link likewise pointed at `reflex-web/tree/main`
  and produced `…/<path>/.md` (extra slash, missing `docs/` prefix).
  Use `reflex/blob/main/docs<path>.md` so the link lands on the
  actual markdown file.
- Add `.github/ISSUE_TEMPLATE/documentation.md` so the
  `?template=documentation.md` URL resolves.
