Bug: Some CLI arguments are undocumented

[eric-seppanen]

Describe the bug

Some CLI arguments appear in cargo deny -h but are undocumented in the book:

• --locked
• --frozen (help text says "Require Cargo.lock and cache are up to date"; what cache is this referring to?)
• --allow-git-index

The fetch subcommand is not mentioned in the book at all.

One argument appears in cargo deny list -h but is undocumented in the book:

• --config

Additionally, there is an out of date description of cargo deny list --color but that argument was moved to the top level (common) arguments.
