fix: repair broken template URLs and template file references

denbeigh2000/coder-templates was restructured into a single module;
the aws-nixos, aws-spot-nixos, and aws-spot-nixos-graviton sub-paths
are 404. Consolidate to a single entry pointing at the repo root.

ElliotG/coder-oss-gke-tf was renamed to ElliotG/coder-oss-tf and
redirects. The Tutorials bullet and the Automation bullet pointed at
the same repo through the redirect, which awesome-lint flagged as a
duplicate link once both URLs were canonicalized. Drop the Tutorials
copy and keep the Automation entry, which is the natural home for
'provision Coder with Terraform'.

PR and issue templates referenced ../blob/main/CONTRIBUTING.md, which
is not a valid filesystem path and broke local file resolution in
lychee. Switch to the absolute GitHub URL so the link works both as a
clickable link and as a target lychee can verify.

Verified locally with curl against every URL in the repo plus
prettier, awesome-lint, and typos.

This change was prepared by Coder Agents.
