soroban-cli install instructions are incomplete on Ubuntu 22.04

What version are you using?

I tried to use 0.8.0

What did you do?

I tried to install soroban cli using docs on Ubuntu 22.04 on amd64 platform.

Exact steps I followed:

1. I run cargo install --locked --version 0.8.0 soroban-cli. This failed with the following:

   Compiling proc-macro2 v1.0.56
error: linker `cc` not found
  |
  = note: No such file or directory (os error 2)

2. To work around the problem I install gcc using sudo apt-get install gcc
3. I retried cargo install --locked --version 0.8.0 soroban-cli. This time if failed with:

  running: "c++" "-O3" "-ffunction-sections" "-fdata-sections" "-fPIC" "-m64" "-Wall" "-Wextra" "-o" "/tmp/cargo-install6vzfsz/release/build/link-cplusplus-cb722335163fd5c9/out/ffae553e737ce720-dummy.o" "-c" "/tmp/cargo-install6vzfsz/release/build/link-cplusplus-cb722335163fd5c9/out/dummy.cc"

  --- stderr

  error occurred: Failed to find tool. Is `c++` installed?

4. To work around this I installed c++ using sudo apt install g++

What did you expect to see?

I expected install instructions to work on a vanilla Ubuntu 22.04 system.

What did you see instead?

I had to install two Ubuntu packages in order to install the CLI: gcc and g++

You should be able to use cargo-binstall, which would download a built binary.

First need to install cargo-binstall:

cargo install cargo-binstall

Or install cargo-binstall as they recommend:

curl -L --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/cargo-bins/cargo-binstall/main/install-from-binstall-release.sh | bash

Then can install soroban-cli:

cargo binstall soroban-cli

@willemneal thank you for extra info. I have not tested this but if those commands work and avoids pulling build dependencies then I'd fully support switching official docs to them.

cargo bininstall soroban-cli will be added to the docs (as well as updating cargo install instructions to include gcc and g++) as part of this issue
