Add nvm installation to install step.

[kabalin]

Install 0.39.7 explicitly as part of vendor installation, so we have control over the version we use.

For cases where nvm is not required (pre-installed in the image, use --no-nvm param for install command)

Fixes #309

Hi @kabalin, this looks good enough. I've just added a couple of details for your consideration.

And then there is the thing (discussed in the chat) about, in some of the tests, always remove any potential $HOME/.nvm dir that may be there to ensure that things are installed (or skipped) properly.

Feel free to merge it once amended, 100%.

One last suggestion, maybe I'd try, with some real plugin, both using 22.04 and 24.04 and verify that it's working in both cases. Sure (99%) it does, but trying with a real plugin is reassuring, IMO.

Ciao :-)

Converting this to draft due to ubuntu 24.04 incompatibility (different default installation dir), we might get back to this in future.
