Error when .env file has empty lines

[razak17]

I get this error when the .env file I'm using contains empty lines

E5108: Error executing lua ...al/share/rvim/lazy/kulala.nvim/lua/kulala/parser/e

I think we need a nil check on line 33 in env.lua, where env[key] is set to value.

for _, line in ipairs(dotenv_env) do
  local key, value = line:match('([^=]+)=(.*)')
    env[key] = value
  end
end
