Relax Node.js version to ^14.20.1 and bump .nvmrc to v14.21.3 (#…

…3463) (#3479) (#3486)

* `engines.node` is relaxed from `14.20.1` to `^14.20.1`: yarn and OSD will allow versions 14.20.1 or greater, but less than 15, to be used but do not impose upgrading to avoid being a breaking change. Users will be able to install any version of Node.js that satisfies `^14.20.1`, moving ahead without waiting for a change in OSD when new versions are released.
* `.nvmrc` is bumped to the latest security patch: `14.21.3`
