refactor(ui-scripts): relocate lint command out of legacy lib/test/ folder

Move lint.ts from lib/test/ into lib/commands/, alongside the other
yargs command modules (bump.ts, server.ts, etc.) it's registered with
in commands/index.ts. The test/ directory dates back to when ui-scripts
merged in the separate ui-test package; lint.ts never followed the
other commands when they were reorganized.
