[lint] Add envs and globals (#1255)

This commit adds envs and globals to configurations to remove wrong errors.

NOTE

"node" in "env"  <-- Removes 'process' is undefined error
"mocha" in "env" <-- Removes 'test'/'suites' is undefined error
"Thenable" in "globals" <-- Removes 'Thenables' is undefined error. Thenable is defined in node_modules/@types/vscode
"NodeJS" in "gloabls" <-- Removes 'NodeJS' is undefined error. Ref Chatie/eslint-config#45
