feat: test output color

[jaymorelli96]

Hi @fredrikaverpil this is what I came up with. I have also updated the documentation. This option is false by default.

I would like to add a screenshot of how it looks but it seems that I don't have access to the assets folder?

Also, I haven't included tests for this, not sure if it is expected for this?

Please let me know if it follows the conventions and it is idiomatic, as I said I don't have experience with Lua and plugin development. The changes are very small, so not sure if I can get much feedback from it 😄

Example of how it looks:

Hey @jaymorelli96 thank you for this, it looks and works really nice!
I especially like how the colors match up with the color scheme in use.

I also actually think we can make this the default, so I have given some suggestions on changes. 😄

Can you also just please add this into the options.lua:

https://github.com/fredrikaverpil/neotest-golang/blob/main/lua/neotest-golang/options.lua

local opts = {
  runner = "go", -- or "gotestsum"
  go_test_args = { "-v", "-race", "-count=1" }, -- NOTE: can also be a function
  gotestsum_args = { "--format=standard-verbose" }, -- NOTE: can also be a function
  go_list_args = {}, -- NOTE: can also be a function
  dap_go_opts = {}, -- NOTE: can also be a function
  testify_enabled = false,
+  colorize_test_output = true,
  warn_test_name_dupes = true,
  warn_test_not_executed = true,

  -- experimental, for now undocumented, options
  dev_notifications = false,
}

And also add colorize_test_output into the tests, so that they pass:
