Add .nvmrc file to specify node version

[petele]

Quickly select the right version of node when using nvm for the repo.

Huh, does nvm support .tool-versions? I use asdf for this and have it ignored, but it would be nice to check in something like it.

(I'll see if asdf could use .nvmrc too.)

[petele]

Interesting - I don't use asdf, and am not familiar with it. But, it doesn't look like it does. :(

[ddbeck]

OK, I couldn't find a way to consolidate on a single file. How about we just set this to be consistent with .node-version and be done with it?

Suggested change

	22
	18

[petele]

I tried running it with 18.16.1 and get an error that I don't get with 22.4.1. @tropicadri mentioned she was having problems with 18 as well and that 22 worked for her. I'm OK with going with 18, but we'll need to specify a subversion as well.

Which version are you running?

Node.js v18.16.1

[ddbeck]

Ah ha. It needs to be >=18.20, which is when import attributes landed in Node.js.

[petele]

Got it - changed it to the official Hydrogen build
