Fix typos in documentation and a code comment

- doc.md: 'Ifyou' -> 'If you'; remove duplicate word in 'my the network adapter'
- speedtest.js: 'nonexistant' -> 'nonexistent' (comment)
- doc_docker.md: 'shoud' -> 'should'

 * __`TELEMETRY`__: Whether to enable telemetry or not. If enabled, you maybe want your data to be persisted. See below. Default value: `false`
 * __`ENABLE_ID_OBFUSCATION`__: When set to true with telemetry enabled, test IDs are obfuscated, to avoid exposing the database internal sequential IDs. Default value: `false`
