Rollup merge of #118323 - onur-ozkan:better-error-for-incorrect-profiles, r=clubby789

give dev-friendly error message for incorrect config profiles

before this change, an incorrect profile would result in the following error:

```sh
...
...
  File "/home/nimda/devspace/onur-ozkan/rust/src/bootstrap/bootstrap.py", line 1088, in bootstrap
    with open(include_path) as included_toml:
         ^^^^^^^^^^^^^^^^^^
FileNotFoundError: [Errno 2] No such file or directory: '/home/nimda/devspace/onur-ozkan/rust/src/bootstrap/defaults/config.aaaa.toml'
```

with this change, the error message is now:

```sh
...
...
  File "/home/nimda/devspace/onur-ozkan/rust/src/bootstrap/bootstrap.py", line 1088, in bootstrap
    raise Exception("Unrecognized profile '{}'. Check src/bootstrap/defaults"
Exception: Unrecognized profile 'aaaa'. Check src/bootstrap/defaults for available options.
```
