chore(3p/sources): Bump channels & overlays (OpenSSL edition)

* //ops/machines/whitby: Disable grafana, since the grafana module was
  changed upstream in a way that our configuration no longer works.
  Since the OpenSSL security update is relatively pressing, adapting the
  grafana configuration beforehand is not a hard requirement. See
  https://github.com/NixOS/nixpkgs/pull/191768.

* //tools/depotfmt: keep Go at version 1.18 to forgo a reformat of the
  tree.

* //nix/buildGo: keep Go at version 1.18, as 1.19 changed the CLI
  interface (?) in a way that breaks buildGo.

* //3p/overlays/tvl: drop upstreamed tdlib upgrade.

* //3p/overlays/tvl: patch buf to work around breakage due to git 2.38.1

TODO items for Go are tracked in b/215.

+    Fix git unit test by using fake git server rather than file:// (#1518)
+    
+    More recent versions of git fix a CVE by disabling some usage of the
+    `file://` transport, see
+    https://github.blog/2022-10-18-git-security-vulnerabilities-announced/#cve-2022-39253.
+    We were using this transport in tests.
+    
+    Instead, use https://git-scm.com/docs/git-http-backend to serve up this
+    repository locally so we don't have to use the file protocol. This
+    should be a more accurate tests, since we mostly expect submodules to
+    come from servers.
