Description:

This PR fixes a spelling inconsistency in the documentation. The word "initialising" has been changed to "initializing".

Issue:

• The word "initialising" is the British spelling, whereas "initializing" is the preferred American English spelling in programming documentation. Using consistent American English spelling in code-related documentation is important to ensure clarity and uniformity across projects.

Importance:

• Standardizing spelling across the documentation helps maintain professionalism and ensures the documentation aligns with the conventions commonly used in the software development community. This small change contributes to a more polished and consistent user experience.

Please review and approve the change.
