Fix examples

[Madoshakalaka]

The demo wesites are down because trunk failures are ignored and empty content was published.

This fixes the build failures by using the latest wasm_opt (version_122)

Additionally

• we emit warnings when outdated wasm-opt is detected for the example crates.
• we provided a tool to update wasm-opt in batch via cargo r -p build-examples -b update-wasm-opt
• correctly exclude wasi_ssr_module because it doesn't need trunk (it has been failing silently in the worflow since last year)
• exit with non-zero exit code when trunk fails to avoid publishing empty examples
• only pass getrandom_backend cfg for examples that need it. see rand 0.8 -> 0.9 #3808 (review)
