rover dev does not listen for .env file changes

[UpcraftLP]

With https://github.com/apollographql/rover/pull/2730, rover dev now parses .env files. However, unlike all other files (router config, supergraph config, subgraph schemas, ...), it does not monitor that file for changes, and does not reload when the env file is changed.
