nvm v0.40.0 introduced error if .nvmrc exists

[Skenvy]

Description

See nvm-sh/nvm#3405.

Prior to the current nvm version, you could source $NVM_DIR/nvm.sh without issue, but the current nvm version, v0.40.0 appears to cause an error when trying to source, if you already have an .nvmrc present.

Hi @Skenvy , the only possible solution is : Downgrade to a stable version of nvm (e.g., v0.39.7) that does not exhibit this issue until a fix is released . regards

@vidyasagarnimmagaddi How long is it likely to be before the runners' installed version could be updated to the latest version that includes the fix, https://github.com/nvm-sh/nvm/releases/tag/v0.40.1
