added bat config, changed broken theme sourcing from ryan4yin source

  config to functional one

for future reference, the issue raised this error:
error: A definition for option `home-manager.users.defin.programs.bat.themes.catppuccin-mocha' is not of type `strings concatenated with "\n"'.
the issue was that nix seemingly cannot turn an array {} into a string,
  and the config option required a string. Comparing against other
  imported themes, I found the readFile command, which has documentation
  specifying that it returns file contents as string, so I simply used
  that solution.
