Editorial improvements to Guide to Core ML Tools

[cpompeo]

This commit makes editorial improvements to some source files for Guide to Core ML Tools, affecting 19 files related to new Core ML Tools APIs announced at WWDC 2024 within three top-level sections (Unified Conversion, Optimization, MLModel):

Unified Conversion --> Conversion Options --> Stateful Models Optimization --> Optimization Workflow Optimization --> Palettization Optimization --> Linear Quantization Optimization --> Pruning Optimization --> Combining Compression Types Optimization --> Conversion MLModel --> Multifunction Models

Here are the categories of changes:

• Normalize spelling (lookup table, data-free compression, fine-tuning, post-training, submodel) in accordance with Apple Style Guide and industry standard
• Fix typos, spelling errors, formatting errors, and grammatical errors
• Modify phrasing to improve clarity for the reader
• Fix instances of numbers to align with Apple style (digits 1-10 spelled out in non-code contexts, renaming links to be article titles instead of the word "here" or "this page")
