clarinet doesn't build on linux using cargo

[xoloki]

Running ubuntu-22.04, I tried to build clarinet on linux using the instructions in README.md. It failed trying to build v8:

error: failed to run custom build command for v8 v0.47.1

Caused by:
process didn't exit successfully: /home/x/src/clarinet/target/debug/build/v8-e3ada70f212e5cbd/build-script-build (exit status: 101)

Python downloader failed, trying with curl.

The problem seems to be that the build implicitly requires either python or curl, but README.md does not list them in the required dependencies:

sudo apt install build-essential pkg-config libssl-dev
