Make runner show a summary of failed steps at the end of the execution

[tiziano88]

I think it is great that this command runs all the steps even if something fails in between.
I suggest logging a summary of the failures or the list of failed steps in the end, so that one does not have to go through the entire log to locate the problem.

Should it only apply to run_ci?
If so, we need to also add a name for each Step, and only show top-level steps (like run_examples_rust or run_tests) and don't show low level steps (like build_wasm_modules).

Adding a PR #1286.
Error summary in the end will look like an exact list of failed steps:

Finished with errors:
 ❯ examples ❯ hello_world ❯ build application ⊢ [ERROR]
