When using plenary.job with LuaLS running, using Job:new resulted in an error saying that there were missing required fields:

These fields are the defined methods on Job. Since Job:new was annotated as accepting as param o a value of type Job, LuaLS is expecting o to have all of the fields of Job. This obviously isn't how Job:new is intended to be used.

This PR adds a separate type definition for a JobOptions, containing all of the field annotations originally on Job. It also makes the Job class definition inherit these fields. It then makes Job:new accept a JobOptions instead of Job for param o. This also adds string[] as an acceptable type for o to support that usage pattern.

There is one other unrelated change (happy to drop if it's not agreeable): setting uv to vim.uv or vim.loop, since vim.loop will be deprecated. This change also resolved several diagnostics raised by LuaLS/LazyDev in this module.

Thanks!
