Node 9 is specified in the Dockefile while the app is build from Node 10 in Makefile

Reproduction steps

1. Notice the use of node 9 in the Dockerfile:
   • https://github.com/jenkins-infra/uplink/blob/72808854ccdadaa52bcf32e85a4367605b96e331/Dockerfile#L1-L11
2. Notice the use of node 10 in ./tools/node/:
   • https://github.com/jenkins-infra/uplink/blob/72808854ccdadaa52bcf32e85a4367605b96e331/tools/node#L30
3. Notice the use of node 10 in the docker-compose file (not used in build, just FYI)
   • https://github.com/jenkins-infra/uplink/blob/72808854ccdadaa52bcf32e85a4367605b96e331/docker-compose.yml#L12
4. check output of npm version in build logs (added in #47)

   { uplink: '1.0.0',
   npm: '6.14.12',
   ares: '1.15.0',
   brotli: '1.0.7',
   cldr: '35.1',
   http_parser: '2.9.4',
   icu: '64.2',
   modules: '64',
   napi: '7',
   nghttp2: '1.41.0',
   node: '10.24.1',
   openssl: '1.1.1k',
   tz: '2019c',
   unicode: '12.1',
   uv: '1.34.2',
   v8: '6.8.275.32-node.59',
   zlib: '1.2.11' }

Expected Results

Same version of node used in the Dockerfile and in the Makefile.

Actual Results

Mismatch between node versions used in Docerfile and in the Makefile.
