fix(theme): fix getSidebar's buggy logic when supporting subtree-lift…

close #4841

Description

This PR resolves when sidebar config object owns a uplifting subtree node (by duplication), getSidebar will match the obviously wrong dir links, for example described in issue #4841, /api-examples.md will be matched to /a.

Not only when there is subtree lifting will the bug reproduce, and I'm also afraid when doing matching of /api-b/a.md, it will be matched to /api/, and I also proved this guess, the sidebar object is, can also see my repo's newest commit:
