Set default speeds to previous values

[PaulBouchier]

Set linear & angular speeds & accelerations to what they were in the humbe-based nav2 param file

You'll be glad to know that the jazzy branch of this repo works on both gazebo and hardware (tested with my minniebot robot).

I might have misinterpreted your comment about default parameters to be broader than you meant. Re-reading your comment, you highlighted some speeds that were different. I went back and checked the linear and angular speeds & accelerations in this PR's nav2 param files vs the humble-based nav2 param files, and found some discrepancies and rectified them to make them match the humble param file.

I feel it's working better than it was previously with these changes. It doesn't rotate so fast, and doesn't tend to overshoot on in-place rotation at the end of a move.

I am using linorobot2_hardware from @hippo5329 repo on the robot and micro-ros over wifi for this testing because I don't have a robot computer and the upstream linorobot2_hardware repo doesn't support micro-ros over wifi. I will both put a robot computer on the robot and test the upstream linorobot2_hardware against this jazzy branch, and also submit a PR to support micro-ros over wifi in the upstream repo.

I'm new to github workflows and to submitting PRs when my fork is 2nd in line, so I hope I did everything correctly. All the requested changes should be in place, and waiting for you to pull the trigger on the workflow.

Just posting the initial review here for reference:
#157 .

Let me run this one more time in sim and this should be approved anytime soon.
