Snazz up the build code a little bit

* Add help target
  - woot
* Rename make check to make pass
  - It was originally this way and it was better. I immediately
    regretted changing it.
* Rename make typecheck to make check
  - yeah hopefully not too confusing. Probably nobody uses this
    but me anyways.

 ## Things to know
 
 * See the Makefile for tasks
-* `make check` will run everything you need to be sure things are healthy
+* `make pass` will run everything you need to be sure things are healthy
 * in your lazy config, set dir = "<the plugin's dir>"
 * use util.R in init.lua for the plugin to hot reload in your current dev environment
 * use `util.log` to print to the fs, and `tail -f ~/.local/share/nvim/treewalker/debug.log` to read from it
