Suggest correct names for fields etc

Describe the Bug

Given:

long_variable_name = 1
y = long_variuble_name

We produce the error:

ERROR 2:5-23: Could not find name `long_variuble_name` [[unknown-name](https://pyrefly.org/en/docs/error-kinds/#unknown-name)]

We should suggest using long_variable_name. Starlark already does this.
