You have several options.
1. Image:Mode:Grayscale this will convert your gif to grayscale
You can then convert it back to GIF (e.g. Image:Mode:Indexed, and save
with the .gif extension)
2. Image:Mode:RGB convert the image to RGB, then
Layer:Colors:Desaturate will give you grayscale.
Image:Mode:Indexed to get it back to indexed, and save with .gif
extension as before.
