fix: resolve workspace folder in config path for better compatibility

see #66

this allows use of relative path to the config file and  variable use and makes the following valid configuration options:

{
  vale.valeCLI.config: /home/patrick/github.com/davidsneighbour/kollitsch.dev/src/config/vale/vale.ini,
  vale.valeCLI.config: /src/config/vale/vale.ini,
  vale.valeCLI.config: ./src/config/vale/vale.ini,
}
