chore:fix: restrict node engine versions

[sripwoud]

I ran into the following error when running yarn demo with node versions higher than 17.0.0:

Error HH604: Error running JSON-RPC server: error:0308010C:digital envelope routines::unsupported

It looks like it is due to Node 17.0.0 starting to use OpenSSL3
webpack/webpack#14532 (comment)

It can be solved for instance by:

• restricting the node engine versions in top level package.json
• or using the --openssl-legacy-provider NODE_OPTIONS flag as suggested here

I suggest the first solution because

• I think unless one is familiar with the flag --openssl-legacy-provider, it will raise questions when one sees it used in a script
• we would need to add this flag to all the scripts that need it
• using engines in package.json is probably a more common way to avoid such compatibility issues.

Test plan

• on main branch:
  • yarn demo using NodeJS version >= 17.0.0: you'll see the error message mentioned above
  • yarn demo using NodeJS >= 16.0.0 < 17.0.0: script will execute without issues
• on this branch:
  You'll be warned that you must use a node version between 16.0.0 and 17.0.0 to run the script

  The engine "node" is incompatible with this module. Expected version ">=16 <17". Got "18.9.0"
  

(I didn't test with versions lower than 16.0.0)
