[GH-974] Add bushes to merliot

[tvillegas98]

Motivation

Add missing bushes to Merliot. to bring more Dynamism to matches
Closes #974

Summary of changes

I added a lot of new bushes. You’ll notice in the browser that some are circular while others are square, this was intentional because some bushes were harder to implement as circles than as squares.

Remember that these bushes are just approximations to what we what in our current map, we'll make it them more precise in further iterations, either by adding more bushes in the front or modify the backend

How to test it?

• Run the seeds again by doing make start
• Play the game either in the browser or unity client and check that new at least most of the bushes are cover correctly
