docs: remove extra space after backtick in 'module' configuration

[ltndat]

Problem

There was an unnecessary space after the backtick in the markdown file for the Module of Content Configuration challenge, which caused formatting inconsistencies.

Solution

• Removed the extra space before the backtick to maintain consistent formatting in the challenge description.
• Ensured the file aligns with the other markdown files in the curriculum.

Test

• Visually reviewed the markdown content.
• Verified that no other formatting issues were present in the file.
• No errors reported when viewing the file in the curriculum.
