Closes compiler-explorer/compiler-explorer#8706.

Adds 44.0.2 and 45.0.0 to the wasmtime targets in bin/yaml/wasm.yaml:

  • 44.0.2 — security backport addressing GHSA-2r75-cxrj-cmph (WASI path_open(TRUNCATE) bypasses FilePerms::WRITE). CE doesn't expose WASI filesystem permissions to user code, so the advisory isn't exploitable here, but no reason to ship the vulnerable patchlevel. Picked over 44.0.1.
  • 45.0.0 — the next major. Release notes.
