Previously, a cross-reference to another document could only be created
by writing the full path to the document starting from the
Documentation/ directory.
Extend this to also allow relative paths to be used. A relative path
would be just the path, like ../filename.rst, while the absolute path
still needs to start from Documentation, like Documentation/filename.rst.
As part of this change, the .rst extension is now required for both
types of paths, since not requiring it would cause the regex to be too
generic.
