Typo in Coding Style Guide

Describe the bug

There are several typos that I observe in the Coding Style Guide doc.

Avoid introducing TODO (#XYZ): ... comments in the files and instead try to do things correctly the first time. If you are going to add a TODO comment in any file then there needs to be (at minimum) a full comment and justification explaining what has been tried and what the issue is. The TODo should also reference an issue created on GitHub for thracking the problem.

I would be happy to fix this issue, as I have just passed my TOEFL certification, so you can assign it to me.

Open Coding-style-guide.md from the linked page and go to the General section. Review the TODO guidance where the misspellings appear, correct “TODo” to “TODO” and “thracking” to “tracking,” then verify both typos are fixed in the rendered documentation.
