Version of Hardhat

2.22.3

What happened?

I have a problem to compile Open Zeppelin library

https://github.com/NomicFoundation/hardhat/assets/51862854/b73aabcc-32bf-4d0b-862a-4d82658dbd85

The hardhat error informs that I am using node v22.0.0, but I don't have it installed in my Linux.

Minimal reproduction steps

I am trying to compile a simple smart contract, my node.js is v20.12.2, but when I apply "npx hardhat compile", I receive this message:

WARNING: You are currently using Node.js v22.0.0, which is not supported by Hardhat. This can lead to unexpected behavior. See https://hardhat.org/nodejs-versions

I applied on my Terminal to list all node versions in my linux Ubuntu:
nvm ls

And there is no node version 22.0.0 in my computer:

v20.0.0
-> v20.12.2
system
default -> 20 (-> v20.12.2)
iojs -> N/A (default)
unstable -> N/A (default)
node -> stable (-> v20.12.2) (default)
stable -> 20.12 (-> v20.12.2) (default)

lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)

lts/erbium -> v12.22.12 (-> N/A)

lts/gallium -> v16.20.2 (-> N/A)
lts/hydrogen -> v18.20.2 (-> N/A)
lts/iron -> v20.12.2

Because of this I have this problem to use Open Zeppelin library, with this error:

Hi @engdanilo, I don't seem to be getting the same error:

Can you provide a minimal reproducible example?
