feat(nest): added @nx/nest/plugin with NestJS project detection through nest-cli.json

[vrxj81]

Current Behavior

The @nx/nest plugin does not detect NestJS projects from nest-cli.json, so Nest applications configured that way are not picked up by the plugin.

Expected Behavior

The @nx/nest plugin detects NestJS projects through nest-cli.json.

Manual test steps

• created Nest app using nest new nest-test
• added Nx using nx init
• installed @nx/nest plugin through local path entry in package.json, running npm install and adding plugin config to nx.json ( { plugins: [ "@nx/nest/plugin"} )
• removed default nest NPM build target from package.json
• ran nx show projects
• ran nx show project nest-test
• ran nx build nest-test twice (target and cache test)
• ran nx serve nest-test
