update Contract Verification docs

[davidstrouk]

What changed? Why?

• Updated the "Contract Verification" article, addressing issue Docs Request: Manual verification article is unclear and missing links. #342.
• Added direct links to sepolia.basescan.org throughout the article for improved clarity.
• Revised language to emphasize the need for users to use sepolia.basescan.org for contract verification and interactions on the Base Sepolia testnet.
• Enhanced sentence structure and flow while preserving all essential information.

Notes to reviewers

This PR draws inspiration from #345, which was closed due to inactivity.

How has it been tested?

• Reviewed the revised article for clarity, accuracy, and completeness.
• Verified all links to ensure they correctly point to relevant pages on sepolia.basescan.org.
• Followed the updated instructions to verify and interact with a contract on sepolia.basescan.org, confirming that the described process works as intended.
