tree: bump to 2.1.3

Changelog: version 2.1.3 (07/09/2024)
  - Mostly a brown-paper bag release to fix the below regression and add a
    feature I forgot to add.
  - Fix regression in search() function that broke --fromfile (Florian Ernst)
    (caused by removing too much code while fixing premature sort for
    --fromfile)
  - Allow the -L option to accept its parameter immediately (with no space)
    instead of requiring it be the next option word. (Trevor Gross)
