Adapt bookmarks native url to more possibilities
Enhanced bookmark uses same url pattern with original bookmark page. The
original bookmark url pattern assumes any number after "/" is the folder
id.
However, in enhanced bookmark, we allow patterns as follows:
folder: chrome-native://bookmarks/folder/1234
filter: chrome-native://bookmarks/filter/wikipedia
uncategarized: chrome-native://bookmarks/uncategarized
