This pull request makes several minor corrections and improvements to the Instructions/Exercises/04b-web-iq.md file, focusing on language clarity, grammar, and usability tips. The changes help ensure the instructions are easier to follow and more accurate.

Language and grammar corrections:

• Corrected spelling and phrasing issues throughout the instructions, such as "up to date" to "up-to-date", "you Azure subscription" to "your Azure subscription", and "attemot" to "attempt". [1] [2] [3]
• Fixed wording in instructions to improve clarity, such as changing "the tool bar the top of the page" to "the toolbar at the top of the page" and "a images" to "images". [1] [2]
• Improved phrasing for follow-up prompts, e.g., "follow up prompt" to "follow-up prompt".

Usability improvements:

• Added a tip about zooming out in the browser if the copy button for the API key isn't visible or accessible.
