[Lldb-commits] [lldb] [lldb][docs] Make it clear we require SWIG >= 4 (PR #208687)

[David Spickett via lldb-commits]

https://github.com/DavidSpickett created https://github.com/llvm/llvm-project/pull/208687

We said this in "Preliminaries", but later had a note about SWIG < 4. So if you hadn't read the first part properly, it looked like we allow < 4.

We do not, so I've removed the note about < 4 and
added SWIG to the "Optional Dependencies" table
for extra emphasis.

-There is an [incompatibility](https://github.com/swig/swig/issues/1321) between Python version 3.7 and later
-and swig versions older than 4.0.0 which makes builds of LLDB using debug
-versions of python unusable. This primarily affects Windows, as debug builds of
-LLDB must use debug python as well.
