Update README: package cmake3 is missing in Ubuntu 22.10 repository but package cmake is there

[ivan-karlovich]

There is no package cmake3 in Ubuntu 22.10 repository. At the same time package cmake is present there. The reported version is 3.24.3:

$ sudo apt install cmake3
...
E: Unable to locate package cmake3
$ sudo apt install cmake
...
$ cmake --version
cmake version 3.24.3

Probably, makes sense to update README to reflect this fact.

Thanks! Fixed in f97b0541bfa24b6a1977ae0c5f80ad27bc5bbcff

Those instructions were written long ago, back when cmake2 and cmake3 had to peacefully co-exist.
