Remove an Extra Period in README.md

[JessicaLucindaCheng]

Fixes N/A

What changes did you make?

• I removed the extra period after "how to evaluate if its a great idea".

Why did you make the changes (we will use this info to test)?

• I made the changes because I need to re-activate the repo to see if it will generate a new issue when the Google Form "Automation Proposal".
  • This is related to ER: Build a tool to verify activities of HfLA members hackforla/website#4186, where it was decided by Bonnie that the implementation should move to this repo, so I filled out the "Automation Proposal" Google Form but a new issue wasn't generated.
