Deploy issue: Error: error:0308010C:digital envelope routines::unsupported

I followed the readme and used nvm to switch to node 12 (previously I tried with node 16 LTS, same issue)

Environment: Fedora Linux (Fedora 36).

```
nvm use
Found '/test-dapp/.nvmrc' with version
Now using node v12.22.12 (npm v6.14.16)

Same issue with yarn build & yarn start

The `Error: error:0308010C:digital envelope routines::unsupported` issue seems a "well known" issue, in fact I remember I had this issue in a couple of other repos too, and the solution was to use node LTS. Well now I'm using node LTS and the issue is there.

I tried also what people suggest if you google search how to fix this:

```
export NODE_OPTIONS=--openssl-legacy-provider
```

Then tried again:
```
yarn deploy
/usr/bin/node: --openssl-legacy-provider is not allowed in NODE_OPTIONS
```

The option to use openssl legacy is not allowed.

Can you please suggest a fix or even better push a fix so that when users clone this repo on a fresh machine and follow the instructions in the `README` it works out of the box?

A plus would be to support also the actual LTS version v16.x since v12 is a bit oldish.

Thank you.

Start with README, deploy.sh, and the webpack build invoked by yarn deploy; reproduce the failure on Node 12 and Node 16 in the Fedora environment described. Trace the OpenSSL-related webpack error and update the documented setup or build configuration so a fresh checkout can deploy successfully, then verify yarn build and yarn start as requested.
