Update ubuntu-jammy.md

[LiorKogan]

Starting with 8.2, the cmake step is required in Ubuntu 22.04 as well (copied from Ubuntu 20.04 instructions)

Thank you, @LiorKogan!

@LiorKogan I'm curious why pip is used to install CMake. Any issues with the CMake version shipped with Ubuntu 22.04?

$ grep '^VERSION=' /etc/os-release
VERSION="22.04.5 LTS (Jammy Jellyfish)"
$ cmake --version | head -n 1
cmake version 3.22.1

It is already listed in the apt-get install command above the new section. And personally, I prefer downloading from there since it feels a bit safer (e.g. less risk of typo-squatting with Ubuntu archives compared to PyPI

@collinfunk,
Starting with a clean Ubuntu 22.04 Docker image, with cmake 3.22.1, we fail to build RediSearch as part of Redis 8.2.1.

I didn't involve the RediSearch team. I simply applied the same cmake upgrade we use with Ubuntu 20.04.

Trying to build with export IGNORE_MISSING_DEPS=1, I see the following failure:

This doesn't happen after upgrading cmake.

@LiorKogan Thanks. It looks like the Ubuntu one is too old. The current patch works well then.
