[mdqst]

Description:

This update addresses a minor typo in the comments for WORLDCHAIN_UPPER_SWAP_GAS_LIMIT and ASTROCHAIN_SEPOLIA_UPPER_SWAP_GAS_LIMIT. The word "divivde" has been corrected to "divide".

While the typo does not affect functionality, maintaining accurate and professional documentation is essential for code clarity and developer communication. Small fixes like this contribute to a cleaner, more reliable codebase and ensure that future contributors can easily understand the context without distractions.

No code functionality has been altered in this change.
