ToolExecutionError description (#762)

we actually don't want to deprecate ToolExecutionError

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Low risk: behavior change is limited to no longer emitting a
`DeprecationWarning` when `ToolExecutionError` is instantiated, plus a
patch version bump.
> 
> **Overview**
> `ToolExecutionError` is no longer treated as deprecated: the
`warnings` import and runtime `DeprecationWarning` emission were
removed, and the class docstring was updated to describe it as the base
exception for errors raised from within a tool body.
> 
> Bumps `arcade-core` version from `4.2.2` to `4.2.3`.
