Typo in instructions - "riscof arch-tests" command is wrong

[gsmecher]

In the following documentation section:

https://github.com/riscv-software-src/riscof/blob/69b57e14a01b8e1eb5249ca757f3d08a1a6e2c72/docs/source/installation.rst#cloning-the-architectural-tests

...the command

$ riscof --verbose info arch-tests --clone

should be

$ riscof --verbose info arch-test --clone

(without the plural on "arch-test")

[gsmecher]

Apologies - this is already fixed by #57

[algrobman]

I still see this mistake in online documentation
