Fix grammar in Gemini 3 Pro callout

[dsmedia]

Changes "guides who include migration guides" to "guides, both of which include migration sections."

Fixes:

• "who" → "both of which" (grammar)
• "migration guides" → "migration sections" (they're sections, not separate guides)

Also removed the direct migration link since there are two migration sections (one per guide) and the original only linked to one. Opted to mention them in text rather than link both to keep the callout cleaner. Users can still find them easily via the table of contents in each notebook.

Summary of Changes

Hello @dsmedia, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refines the "Gemini 3 Pro" callout in the README.md file to enhance its grammatical accuracy and provide a clearer description of the available migration content. The changes ensure that the documentation precisely reflects the structure of the migration information, making it easier for users to understand and navigate the relevant sections within the provided guides.

Highlights

• Grammar Correction: The phrase "guides who include migration guides" has been updated to "guides, both of which include migration sections" to improve grammatical correctness and clarity.
• Content Accuracy: The term "migration guides" was changed to "migration sections" to accurately reflect that the migration content is integrated as sections within existing guides, rather than being separate, standalone guides.
• Link Simplification: A direct link to a single migration guide was removed from the callout. This change was made to keep the callout cleaner, as there are now two migration sections, and users can easily find them via the table of contents in each notebook.

Code Review

This pull request improves the grammar and clarity of the Gemini 3 Pro callout in the README. The changes are good, correcting a grammatical error and clarifying that the migration information is in sections, not separate guides. I have one minor suggestion to align the wording more closely with the project's style guide.
