5f6e3dcc2e Python: Revert changes to sensitive data query alert messages 
This partly reverts the changes from https://github.com/github/codeql/pull/10252

Although consistency is nice, the new messages didn't sound as natural.

New alert message would read

> Insecure hashing algorithm (md5) depends on sensitive data (password). (...)

I'm not sure what it means that a hashing algorithm depends on data. So
for me, the original text below is much easier to understand.

> Sensitive data (password) is used in a hashing algorithm (md5) that is insecure (...)

Same goes for the other sensitive data queries.

0e3d520712 Python: Add variables regression test 
As illustrated when running the python file, the non qualified reads in
the `use` method all refer to the global variables, whereas `ex =
func(baz)` are to the things defined on the class.

The important part of the .expected changes is that the _global_
variable `bar` is used inside the function, whereas it's the local
variable for `foo` (on class scope) that is used inside the function
(which is wrong).
