@std/task: fix documentation generation by renaming taskLib to task (#964)

The documentation generation for `@std/task` is broken, and I believe it
is because the table is named `taskLib` and not `task`. We can fix this
trivially by renaming it, and that's honestly worth for consistency
doing even if it didn't fix the documentation.
