doc: gitignore: clarify pattern base for info/exclude and core.excludesFile

The pattern format section describes how patterns are interpreted relative to the location of a .gitignore file, but does not mention the behavior for exclude sources outside the working tree. Clarify that patterns from $GIT_DIR/info/exclude and core.excludesFile are treated as if they are specified at the root of the working tree, so a leading '/' anchors matches at the repository root.
