Update installing-cardano-node with minor fixes (#1008)

* Update installing-cardano-node with Ubuntu 22 &etc

Update installing-cardano-node.md with Ubuntu 22 remarks and some other small fixes

* installing-cardano-node, updated GHCup version

The GHCup Haskell installer, version 0.1.19.2

* Updated requirement for disk space

Updated requirement for disk space

* Now official building manual includes cabal update

Now official building manual includes cabal update, so I think it is time to have it here too.

* Maybe lets have cabal build all everywhere

Now we have for Mac `cabal build all` and for linux `cabal build cardano-node cardano-cli`, I think it will be good idea to have more or less same approach for Mac and Linux

* clarify Secp256k1 requirement by node version
