Add constants to java gearsbot example

[bakedPotatoLord]

Creates a Constants.java file for the java GearsBot example, and implements it everywhere applicable.
There are also a few minor changes including replacing Commands.parallel() with new ParallelCommandGroup() in two instances, and replacing an if gate with a ternary operator in Elevator.java, to improve readability

This fixes half of #1948, but these changes are also required on the C++ example

There are also a few minor changes including replacing Commands.parallel() with 'new ParallelCommandGroup()' in two instances, and replacing an if gate with a ternary operator in Elevator.java, to improve readability

Please revert these. The command factories are preferred over allocating commands directly with new. Also, the if statement was fine as it was.

[bakedPotatoLord]

The unwanted changes are reverted, and the code is formatted. Awaiting workflow run.

Forgot to run wpiformat, but it is formatted now. Awaiting checks. Thank you for your patience.

I'm not sure why the windows debug failed. there were no actual code changes since f68a4a4, which passed the check. Can someone please explain what happened?

I went ahead and reran it- likely just a fluke test failure

Thank you! Is this ready to merge?

Import the nested *Constants classes directly, to avoid the overly long qualification.

fixed by 2b67770. Ready to re-run.

[Starlight220]

Assuming CI passes; looks good.

Now just needs C++.

[prateekma]

Needs formatting fixes. I am ok with merging this and opening an issue to update C++.

[rzblue]

/format

[prateekma]

We should open an issue to update this example for C++ when this is merged.

[Starlight220]

I don't see a reason for a new issue; the one mentioned in the description is enough.

[rzblue]

Just need to make sure the issue doesn't get closed when this PR does
