docs: clarify API key generation link in README

[evatorium]

This PR updates the README to improve clarity around API key generation.

What changed

Replaced the text
"your API key here https://mailtrap.io/api-tokens
"
with
"You can create your API key here https://mailtrap.io/api-tokens
".

Why

The previous phrasing could be misunderstood as suggesting that the key itself should be inserted into code.

39-39: Clear and helpful clarification – LGTM!

The rewording from "your API key here" to "You can create your API key here" effectively removes ambiguity and makes it immediately clear that the URL is where developers should obtain their API key, not where they should paste it. This improves the developer experience and reduces potential confusion during setup.

Tip

📝 Customizable high-level summaries are now available in beta!

You can now customize how CodeRabbit generates the high-level summary in your pull requests — including its content, structure, tone, and formatting.

• Provide your own instructions using the high_level_summary_instructions setting.
• Format the summary however you like (bullet lists, tables, multi-section layouts, contributor stats, etc.).
• Use high_level_summary_in_walkthrough to move the summary from the description to the walkthrough section.

Example instruction:

"Divide the high-level summary into five sections:

1. 📝 Description — Summarize the main change in 50–60 words, explaining what was done.
2. 📓 References — List relevant issues, discussions, documentation, or related PRs.
3. 📦 Dependencies & Requirements — Mention any new/updated dependencies, environment variable changes, or configuration updates.
4. 📊 Contributor Summary — Include a Markdown table showing contributions:
   | Contributor | Lines Added | Lines Removed | Files Changed |
5. ✔️ Additional Notes — Add any extra reviewer context.
   Keep each section concise (under 200 words) and use bullet or numbered lists for clarity."

Note: This feature is currently in beta for Pro-tier users, and pricing will be announced later.
