Support both "versions-maven-plugin" and auto-native DOM/XML

`auto` will detect if the parent `pom.xml` file has the `versions-maven-plugin` configured, and if so, use it to set the version on the parent and all child pom.xml files. If not, then auto will modify the parent and all child `pom.xml` files using a DOM parser and XML serializer. This has the effect of losing formatting. Therefore it then runs the serialized XML through the `prettier` "html" pretty-printer.

This means that if the versions-maven-plugin isn't available, the pom.xml files will be pretty-printed using prettier formatter with the following default settings:

* `printWidth: 120` (configurable - see below)
* `tabWidth: 4` (configurable - see below)
* `parser: "html"`
