Fix tests formatting in graphs/generators/families.py

[slel]

After #30728, some test blocks have TESTS: instead of TESTS::.

The tests in those blocks are in fact never doctested due to that.

Thanks for fixing this. You can set to positive review on my behalf when the patchbot is green.

I don't think some text. :: should be changed unless there is a problem in a particular case (or there is a sage style convention about this). There is nothing wrong with using this style as far as sphinx is concerned: this sphinx web page says "The handling of the :: marker is smart: ... If it is preceded by whitespace, the marker is removed." So some text. :: will show up as a paragraph that ends with a period, instead of a colon, and that seems ok to me.
