Empty files for 009 remain

[greglockwood]

There are still empty files for src/009-cannot-redeclare-block-scoped-variable.problem.ts and src/009-cannot-redeclare-block-scoped-variable.solution.ts in the repo.

It would be good to remove them as they are confusing when you do what I did and clone the repo in Gitpod and just start browsing through the files in the src directory. (I wanted to see if I could solve the errors quickly myself as a more seasoned TS user.)

It took me an embarrassing amount of time before I spotted the directories for exercises 009 and 010. 😳
