S604 shows warning for any type, not just True

[adamhl8]

Say you have something like this:

def do_stuff(shell):
    pass

Calling this function with any argument for shell will show S604, not just True as the warning/documentation implies.

do_stuff(shell="bash")
# S604 Function call with `shell=True` parameter identified, security issue

do_stuff(shell=123)
# S604 Function call with `shell=True` parameter identified, security issue

I believe this is as intended and matches Bandit's behavior -- I think the documentation is the problem.
