[RFC]: add support for displaying suggested corrections in the REPL

### Description

This RFC proposes adding support for displaying suggested corrections in the REPL when a user enters an identifier which does not exist. This functionality would be similar to what is offered by Julia and discussed in https://github.com/JuliaLang/julia/issues/28347.

For example, currently, when a user enters an undefined identifier

```
In [1]: base.abbs( -1.0 )
Error: base.abbs is not a function
```

This RFC proposes extending this to do something along the lines of

```
In [1]: base.abbs( -1.0 )
Error: base.abbs is not a function

Perhaps you meant base.abs, base.abs2, ...
```

There may be other UI options, and we could, similar to Julia, provide suggestions when a user provides an unknown name to `help()` (or other similar built-in REPL commands).

Start by reviewing the REPL behavior described in this RFC and the linked Julia discussion. The proposal does not identify files, tests, or a settled UI; scope would need to be clarified before implementation. Done would mean agreeing on and implementing a way to suggest corrections for undefined identifiers, with possible support for unknown names passed to help().
