Summary: Mailtrap pricing menu updated

Why It Matters: Mailtrap changed how it shows pricing options. This could make it easier for people to pick a plan.

What Changed:

• Remove "INTEGRATIONS" and "SDKs" sections from the main navigation.
• Update the "Pricing" menu to show "Email API/SMTP" and "Email Sandbox" as sub-items.
• Remove the "INTEGRATIONS" and "SDKs" sections from the "Resources" menu.
