prevent crash when use redirection with let/mut (#10139)
Fix #9992 

I mistakenly messed up https://github.com/nushell/nushell/pull/10118 and
this is a cleaned version.

# Description

* This pr changes the panic to errors while parsing `let`, now user will
get the following errors:

* `out+err>` is cached by `parse_expression` but not this, which may be
a potential problem.
* `Commond(None, ..)` remains panic for future bug report because I
don't actually know when/how does it happen

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
