Move Pebble Time Round getting started guide to guides section

Moved the "Getting Started with Pebble Time Round" page from the SDK
section to the guides section under Tools and Resources. This makes it
more discoverable as a guide rather than being hidden in the SDK sidebar.

Changes:
- Move source/round/getting-started.md to source/_guides/getting-started-pebble-time-round.md
- Update front matter to use guide_group: tools-and-resources
- Remove from SDK sidebar in source/_layouts/sdk/master.html
- Add redirects from old URLs to new location
