community[patch]: Load list of files using UnstructuredFileLoader (#16216)
- **Description:** Updated `_get_elements()` function of
`UnstructuredFileLoader `class to check if the argument self.file_path
is a file or list of files. If it is a list of files then it iterates
over the list of file paths, calls the partition function for each one,
and appends the results to the elements list. If self.file_path is not a
list, it calls the partition function as before.
  
  - **Issue:** Fixed #15607,
  - **Dependencies:** NA
  - **Twitter handle:** NA
