dev-cmd/generate-formula-api: add dependencies to internal API.

[MikeMcQuaid]

This should reduce the need to download formula stubs in the vast majority of cases.

Pull Request Overview

This PR adds dependency information to Homebrew's internal formula API to reduce the need to download full formula definitions (stubs) in most cases. The changes include logic to determine which uses_from_macos dependencies should be included based on the macOS version of the bottle tag being processed.

Key Changes:

• Extracts macOS version from bottle tags for version-aware dependency filtering
• Adds logic to include conditional uses_from_macos dependencies based on the :since bounds
• Modifies the formula stub array structure to include a 5th element (dependencies)
• Adds an empty casks key to the formula internal API JSON structure

The formula stub array structure is being changed from 4 elements [pkg_version, version_scheme, rebuild, sha256] to 5 elements by adding dependencies.to_a. However, the consumer code in api/internal.rb (line 127) expects a 4-element array as indicated by the type signature T::Hash[String, [String, Integer, Integer, T.nilable(String)]], and formula_stub method (lines 43-51) only accesses indices 0-3. This will break the expected API contract. The FormulaStub class and consumer code need to be updated to handle the dependencies field, or the type signature needs to be updated to reflect the new structure.

This should be fine to do in a separate PR
