Delete bad BaGLAMa categories

[Former user]

I guess new categories added to BaGLAMa are not validated that they actually exist in Wikimedia Commons. I created the following new categories accidentally:

• "Media%20contributed%20by%20Cumberland%20County%20Public%20Library%20&%20Information%20Center" (GID 731)
• "Media%20contributed%20by%20Ed%20&%20Hazel%20Richmond%20Public%20Library" (GID 732)
