Fix typo in Lesson2-HTML-CSS homework about precourse

[adsingh14]

✅ I just noted the typos.
III. Create an external style sheet and move all of our previous style rules into the new stylesheet.
A. Create a file called styles.css in this folder.
B. MOVE COPY all of your style rules to this new file. (Do not include the style tags!)
C. Place: after your closing style tag.
E. Add a link tag to your html that imports your new css file.

Reason: If we'd move our internal style to external stylesheet (called styles.css), then why we need comment <style> tag in .html file?
