fix(api): add case correction to module_context.load_labware (#14964)

Closes RESC-235 and RQA-2610

# Overview

Fixes the `module_context.load_labware()` method by ensuring that
labware names are converted into lower case before using them in any
part of the code.

The escalations issue above was caused by a cascade of things happening
because the protocol had a module labware loaded with the labware name
written in mixed case. There are a few places where we do string
comparison of the labware names, including when trying to find new
versions of a labware and when looking up LPC offsets for a labware.
These string comparisons would fail because all labware definitions have
lowercase names, and hence would lead to unexpected behavior. It should
no longer create such a problem

# Risk assessment

Very low. Tiny bug fix
