Delete mention of comprehensions differing from Python
Delete mention of comprehensions differing from Python

Under https://github.com/bazelbuild/bazel/commit/c1fe6c55744faba63cd3d364485f040876851444, there is very little difference between Starlark's treatment of comprehensions and Python 3's. (There is significant difference from Python 2 though.)

We actually are still different from Python in the case where an outer var x is both read and written in the comprehension (for x in x), but the Starlark spec currently agrees with Python and the Java Starlark interpreter is just out-of-spec.

Relevant: #9438.
