message: Update YAML config docs
diff: * hello:
  * world:
  * exampleValue: 10
  - * importantValue:
  + * example: 12.2
  + * importantValues:
  * - entry1
  * - entry2
  * - entry3
  * To use the class, at least one YAML configuration file must be added to the class. To do so, use:
  *
  * ~~~{.cxx}
  - * AliYAMLConfiguration config;
  + * PWG::Tools::AliYAMLConfiguration config;
  * config.AddConfiguration(filename, name);
  * // Will only be checked if a requested value is not in the first configuration.
  * config.AddConfiguration(filename2, name2);
  * explicitly specify such an initialization as `std::vector<std::string>` if you don't define it as a
  * variable.
  *
  + * Explicitly, this would look like:
  + *
  + * ~~~{.cxx}
  + * int tempInt = 0;
  + * // True specifies that the value must exist in the config
  + * config.GetProperty({"hello", "world", "examplePath"}, tempInt, true);
  + * std::cout << tempInt << "\n"; // Returns "10"
  + * // Alternatively, you could specify the path explicitly (although not recommended)
  + * config.GetProperty("hello:world:exampleValue", tempInt);
  + * // The type specifies what is returned
  + * double tempDouble = 0.;
  + * config.GetProperty("example", tempDouble);
  + * std::vector <std::string> importantValues;
  + * config.GetProperty("importantValues", importantValues);
  + * // The vector "importantValues" now contains three strings
  + * ~~~
  + *
  * That's basically all there is to using it. For more information, look at the documentation of the various
  - * GetProperty(...) and WriteProperty(...) functions.
  + * GetProperty(...) and WriteProperty(...) functions. The interfaces to both functions are fairly similar.
  *
  * Notes on using shared parameters:
